The guidelines for this extension literally say that a slur targeted at trans people is "not enough" to mark as anti-trans.
The developers have as of recently been exploiting this extension's purpose to mark subsets of the trans community they personally don't like by flagging them as anti-trans while a lot of pro-trans tagged accounts can say highly bigoted things about other groups of trans people such as trans men and non-binary people.
This is no longer an actual add-on to help trans people online but a way for transphobes to pretend they are trans-friendly while harassing trans people

edit: this developer reply is not only using rhethoric to attack non-binary people baselessly by mentioning "binary trans woman" is used against women who transition (usually transphobes wouldn't be in favor of non-binary people either so i dont understand why the claim of "long been used" was even attempted) but also avoiding the clear slur criticism by saying "controversial terms" instead
As a trans woman these kind of attempts to come up with false reasons to muster community in-fighting by falsely tagging non-binary and trans masc people as transphobic while allowing the use of slurs against those identities (like "theyfab") does nothing but make me feel unsafe about the extension if it is being misused in this way to slander and enable harassment of my fellow members of the community

Not trustworthy. Have witnessed many, MANY intersex and non-binary blogs and accounts online be marked red for [checks notes] approaching identities with nuance because the binaries people have constructed don't fit them. Despite enbyphobia being a listed reason to mark someone as transphobic. Meanwhile, many accounts are marked as trans-safe despite literally using transphobic slurs. What happened to, "don't assume someone isn't transphobic because they're trans?" Do not recommend- use your own judgment, it'll be better than whatever these people decide is "transphobic enough."

This extension is unsafe for intersex and transmasc people. Intersex and transmasc people are being marked red for talking about our experiences, identities, and the specific kinds of bigotry we face. A tool that was originally meant to protect trans people is now being used to divide the lgbt community. Intersex people having intersex specific experiences and identities is not transphobic. Transmasc people talking about how transphobia affects them is not transphobic.

Edit: Telling intersex people we aren't allowed to describe our experiences with language that differs from perisex people is wildly intersexist. Erasing intersex identities and experiences is more in line with the goals of TERFs than a transgender intersex person using language differently than you to describe the differences in their experiences. Also, trans women who were afab calling themselves that doesn't force anyone else to do shit. It's literally just them describing their own lived experience.

No longer trustworthy, they're now marking transmen and intersex people as not safe for the crime of -checks notes- not being exclusionist, talking about ways transphobia affects them, and intersectionalism. These discussions are very important to our movement and we shouldn't be redlisting these voices.

echoing the other reviews - using a formerly wonderful tool to silence trans men and intersex folks is a terrible look. eagerly looking forward to a spinoff fork of this from someone less shitty.

editing to follow up to the dev response: at no point did I say trans women should use that terminology? thanks for the ad hominem response that does nothing to address the issue at hand, that accuses us of being TERFs to boot. keeping my review at one stars. i would rate it 0 if i could.

Was v excited about this and used it for tumblr. As a trans man I follow many blogs, trans femme and trans masc. Most of my activist trans masc follows are marked as red for talking about transmisandry and apparently got mass reported. So yeah this isn't useful for trans men. Asking around and apparently there's issues with intersex blogs as well so that's fun. Human bias within the dev team prevails. Thanks for that.

This used to be a really useful tool, but it's now flagging lots of trans and intersex folks for having the audacity to be inclusionist. Allowing bigotry against trans masc, intersex, and nonbinary people in the tos is not a good look!!

Edit to add: developer response absolutely incomprehensible and responding to a problem I did not mention and have never seen anywhere?? Girl help.

Used to be one of my favourite extensions. I cannot express how disappointed I am to see what this has become. Allowing usage of enbyphobic/exorsexist slurs to be considered 'not enough to mark someone as transphobic', while considering those identifying in good faith with typically intersex identities as a valid reason to mark some as transphobic is frankly disgusting. An extension like this was probably doomed to fail at some point, but it's very disappointing to see it happen regardless.

Aside from the problem with the guidelines, the moderation team needs to get a handle on the blatant transandrophobia, because the last 4 red flagged accounts I've seen have just been people discussing transmasc opression. It's very easy to tell when those accounts are also transphobic in some regard and they very much were not. Though I'm going to guess that this is by design. I kept it for a while but it's not catching terfs anymore, just trans people minding their own business that yall disagree with.

edit: developer response is ridiculous. intersex people defining themselves in a way that aligns with their complex personal experiences isnt forcing trans women to label themselves as male at all. i thought we were long past treating other good faith identities as a threat. and ive seen amab transmascs too, in about equal number to afab transfems. funny how you dont mention those. personally as a trans bloke that lot hasnt made me feel threatened! maybe its time to listen to intersex people instead of keeping to your narrow, and frankly biased viewpoint.

cannot emphasize enough how bad an idea it is to trust some random add-on maintainer's curated list to tell you who is a Good Person and who is a Bad Person. even apart from the verifiable misuse of this tool, it is just foundationally a bad idea.

This was once useful for flagging bigots - it is now itself exclusionary.

It's "alright", but it's not as useful as it should be. I've seen *trans* people be *wrongfully* marked as transphobic, over simply asking to be treated with respect for being part of other minorities, or for using microlabels and other niche identities that certain people using this extension have decided are "harmful" and "mocking". It would be a lot nicer to use had I known that I could speak up about struggles and minorities that still aren't "important" to most people without wrongfully being marked as transphobic. Additionally, in the guidelines it says that.... Actual bigotry against trans people isn't enough to get marked as transphobic???

Shinigami Eyes was a great idea and I've enjoyed it for many years. However, I think a new dev team has taken over (or the values of the dev team have changed drastically), as they've now taken it upon themselves to highlight trans people they don't like, including intersex activists, kids using odd labels/neopronouns, transmascs and transfems of color who discuss their unique experiences with transphobia, and transfems who are genderfluid or use he/him pronouns - in short, any trans person who's "cringe" or uses the "wrong" language.

Shinigami Eyes was invented to highlight dangerous transphobes, like TERFs and alt-righters, and it's really disappointing to see it misused to destroy trans solidarity. I'm sorry, but I just don't believe members of my own community are a danger in need of ostracism, just because they say things I don't like.

The dev team needs to get their shit together and stop splitting up our community. Especially in this time, where we need solidarity more than ever.

Edit, since I can't respond directly to the developer's response: Since when are we letting TERFs dictate our language? No one is forcing trans women to do anything. If you let yourself be pushed around by TERFs, and letting TERFs force you to disclose your assigned gender, that is your own problem. You don't have to define yourself by your assigned gender, just because other people do.

Being used to silence people who speak on Intersex issues as well as transmasq topics

Used to be a great way to filter and block transphobes but now the moderators are flagging trans men and intersex people red for speaking on their own experiences with transphobia

used to target actually transphobic people + sites, now just targets anyone who doesnt agree with the creators :< if youre considering installing this anyway, please please please look at what they consider to be a qualifier for red vs green marking first, esp intersex + transmasc people. you can check their guidelines by going to the user page (click the "shinigami eyes" link right under addon title), click "homepage", scroll down to "shinigami eyes website", then to the section labeled "how to label".

I had been happily using this extension for many years. However, infighting that leads to false flagging of transmasc and intersex people for merely talking about their experiences and the uniquely awful transphobia they face is inexcusable. Moderation seriously needs a major overhaul for the sake of the entire trans community. To exclude these voices is what leads to in-fighting and our community to become much more divided, something we absolutely cannot risk having right now more than ever.

But hey, this extension can tell you that the (un)funny white cishet youtube man who may have coughed out a "trans rights" once for the meme is a totally great and reliable trans ally alongside actual advocates working around the clock to fight for trans rights for everyone. So it has it's value there I *guess*.

I used to use this a lot, but now that it marks users negatively based on the personal views of the creators, rather than truthfully whether someone is actually known to be transphobic, means I cannot trust it anymore, so I unfortunately have to mark it poorly.

This extension has the capacity to be misused to silence intersex people and its TOS considers bigotry against nonbinary & transmasc people to be permissible and not enough evidence to mark a person as anti-trans.

This extension was once a very good tool to tell if someone was trans-safe at a glance. Now I'm immensely disappointed with the way it's being handled. Folks who discuss the aggression and oppression that trans men and intersex people experience unique to trans women are not transphobic and now the tool only pushes for community separatism, instead of community solidarity. Moderation needs to be overhauled severely.

What was once a useful extension has become a tool for transphobic bullying and is now useless for identifying actual transphobes OR people genuinely supportive and inclusive of all trans people.

People are marked red for talking about transphobia towards trans men, mascs and transneutrals (INCLUDING trans women speaking up in support) and for petty discourse reasons, yet people can stay marked green while spewing vile transphobia and intersexism as long as it's not about trans women the moderators agree with.

This gives people false impressions of not only potential transphobes, cutting off people who are genuinely supportive and inclusive, but have been marked red either by mass reports or for petty reasons or ARE trans but have an identity that the creators believe is innately transphobic for intersexist reasons, but also fools people into thinking that others are safe and exposing them to vitriolic transphobia towards transmascs, transneutrals and disagreeing transfems, and exclusionary rhetoric that only serves to promote separatism.

Extension might as well be rebranded as a TW(only)IRF identifying extension (that's fine with people using transphobic slang from 4chan as long as it isn't about trans women) since that's basically what it's become.

with the new guidlines of what is considered transphobic or not this extension has become functionally useless for social media so i've stopped using it. not to mention that even before the change of guidelines people were marked green for no reason. my main tumblr account is marked green and i dont even talk abt trans topics on there, all ive done is reblog gofundmes of trans women a couple times which shouldnt be enough to mark someone as green.
the extension works well for news websites though.
