Look, regardless of your opinion on whether "transandrophobia" is real or not, being transphobic towards trans men is still transphobia and is still bad. There should never be a kind of trans person that it is acceptable to be transphobic towards, and just because you are trans yourself doesn't make what you're saying any less transphobic. A gay person can still be homophobic, a trans person can still be transphobic, and I have seen far too many transphobic trans people marked in green because they support trans women while oftentimes putting down or even parroting TERF rhetoric in regards to trans men or nonbinary people.

Giving it two stars because it served its purpose for a good while and I think it would be disingenuous to pretend it never worked; I have had it installed for years at this point and used to regularly contribute by going into transphobic threads and marking every transphobe in red so others knew and could block them, but I've seen too many false greens by this point, along with people marked red that have never said anything about trans people at all let alone say something transmisogynistic. And I don't want to hear the "multiple reports have to be made to get a red mark" argument, it's known there's groups that target people en masse to get a false flag in amidst the genuine flags. And if you are one of the people saying that all the people marked green are trans friendly, you've either successfully blocked and avoided all the transphobes or you're blind to transphobia directed at anyone that isn't transfem.

Finishing up by saying this tool no longer follows its own rules. It has never been exclusively a transmisogyny detector - it is even supposed to encompass exorsexism (listed as "enby-phobia"). Read the extensions own guidelines (shinigami-eyes dot github dot io) before claiming otherwise.

unfortunately it's useless when you can't see why someone was flagged. a lot of people criticizing anti transmasculinity get flagged as red and a lot of straight up bigoted, enbyphobic, people who hate trans men get flagged green with no way to correct that. I'm very disappointed

Haven't had this extension installed for years. Went to see just how bad it's supposedly gotten and. Yeah they weren't kidding. Tons of trans-friendly blogs marked red, and people who will say the most hateful things you've ever read about a group of trans people will be marked green. It has been taken over by those pushing the new wave of radical feminism with a "trans-friendly" coat of paint. And make no mistake: it is absolutely repackaged radfem rhetoric. It serves only to divide the community and isolate vulnerable transfeminine people.

Works exactly how one would expect it to. If you can understand the tenants of transmisogyny, you should be able to find people who also do on your dash. I haven't seen an unjustified green or red mark since using it.

bunch of gamergate mens' rights activist losers giving this one star because they're getting marked for being misogynists. it's literally the exact same gets-laughed-out-of-the-room misogyny but trans flavored.

if you saw a cis man going around saying "androphobia is a real thing and all these whiny feminists are just making things up" you would rightfully call him a loser and a grifter. but you throw trans in front of two of those words and apparently it's real now? use your brain for 5 seconds rather than parroting terf rhetoric couched in "inclusive" language.

Unreliable; frequently flags the wrong accounts

This extension was originally a great concept, but the database has been compromised by inaccurate reporting. A significant number of accounts currently flagged red are run by nonbinary, intersex, and transmasculine creators who actively promote trans-positivity.

Many users trust this tool to help them navigate online spaces safely, but it's currently doing the opposite by promoting false accusations and internal division. The developers need to step in, audit the database, and establish proper verification protocols.

I highly recommend avoiding this tool until it's properly moderated.

why are all trans men marked red? why people saying transandrophobia isn't real are marked green?

me when everyone who's not transfem is a bigot, but apparently not alexander lukashenko

Installed it to check what all the drama was about, checked only on tumblr.
Reviews claim news articles and such are often marked correctly, which I have not tested and can thus not comment on.

Accounts marked green were a crapshoot between "good trans advocate" and "at bare minimum raising eyebrows with their stances on transmen or enbies".

Meanwhile of all the accounts I follow that were marked red, multiple were positivity accounts for more 'niche' or 'controverse' topics - including accounts for enby-related stuff, xenogenders, or even one that just spreads positivity about all types of plural systems.
At least one of which had nothing to do with transness at all? But I digress.

Multiple accounts that were outspoken about transmasc issues who dared occasionally point out transfems who were hostile towards transmascs were also marked red, despite not being transmisogynistic.

As such, my final verdict:
Either due to a lack of moderation, deliberate misuse by the community, or both, this tool has gone from a good idea to falsely marking innocent users as red for mild disagreements, oft with transphobic intent (how ironic).

I cannot reccommend using it.
If you still decide to use it, at least don't take the red or green markers as definitive - actually check accounts, and consider critically why someone might have been marked green or red.

(Additionally, accounts that praise shinigami eyes to the high heavens whilst unwilling to admit any flaws with it are sus as hell, which is useful when using tumblr as well.)

I don't block anyone without reason and my dash is full of green and empty of red. Even people who occasionally get uindeserved flak are not marked red but remain neutral. I've seen why someone's marked red pretty quickly with rare exception. And the rare exception is just not being sure. People really exaggerate this problem and just don't recognize their transmisogyny. This includes trans women. Oh, I'm also a trans woman since people like to throw that out for extra credibility in these reviews.

Got marked red on tumblr for being therian/otherkin. This plugin is a joke with how much it's used for infighting/discourse and weaponized against people who are intersex, nonbinary, or transmasc(and apparently nonhuman identifying individuals now too)

unfortunately now a transphobic tool... of course i understand wanting to protect my trans sisters but not at the cost of hurting my trans brothers...

I heard pretty bad things, but I used to use this back in the day when it was still good, so I decided to test it. I can confirm; it's bad. It's not the way it used to be.

I did extensive research on who was marked by this extension, and tested on multiple browsers. I went through over 20 tumblr blogs over the course of a couple days. Plenty of the blogs marked red had no history of transphobia even after over an hour of searching their post history. Even one blog, that I'd been following for years and had shown not even the slightest hint of transphobia or controversy, was marked red. I only found one or two blogs marked red that were actually transphobic, and I would not have needed shinigami eyes to tell. It was clear simply from looking at what they wrote in their profiles (self-identifying as transphobic, for example). So, in terms of identifying transphobes at a glance, shinigami eyes has so far not been helpful.

What I find interesting (and concerning), however, is the common thread of blogs marked red. What all blogs marked red that weren't transphobic (which was almost all of the ones I found) shared in common was that they spoke on the issues trans men, intersex people, and nonbinary people face - or, shared positivity and showed kindness towards those groups. Moreover, blogs that were actively hostile towards trans men, intersex, and nonbinary people, tended to more often be marked green. I was more focused on investigating the red blogs, but from what I saw, green blogs were often quite transphobic as well or did not have enough evidence to prove that they were trans-friendly as the guidelines for markings state.

I tried to see if I could correct these issues, seeing as shinigami eyes is, supposedly, community run in their tags. However, clearing someone's name did not update them on other browsers - even after waiting a considerable amount of time for it to hopefully update. This leads me to believe that tagging is only local, and that global tags (what everyone sees) are done by the developers/mod team of shinigami eyes. Therefore, there is no true way to correct someone's marking. I have seen rumors floating that AI is involved in the tagging, but can find no evidence for or against this claim.

TL;DR
This is NOT useful for trans safety. You will end up blocking a lot of innocent people, and possibly following some very unkind people with harmful beliefs.

this extension doesn't work if you care about nonbinary people. plenty of people who post awful things about nonbinary people are marked green, so this extension is not very useful for me.

It used to be good but it's gone downhill more recently. A lot of trans men & transmasc people have been incorrectly labeled as anti-trans because they gently pushed back on being called women & or pointed out that someone was being anti-trans (including pushing bio essentialist transphobe talking points) against trans men/transmasc people in general. It's a pity that it's not as accurate as it used to be.

Holy sh*t this addon sucks now. I used to use it all the time to block TERFs on tumblr/twitter, but now most people marked red are just trans men or intersex people, and on occasion someone marked green will have posted shit like "trans men are just women that want to feel special". This is an amazing extension if you love infighting, petty bullshit and marking people you personally look down on as bigots.

if you hate trans people who don't conform to gender binary, this is for you!

Good idea misused by the bullies in charge. Now useless for identifying anti trans links due to muddying the list with "anyone the dev hates".
