It'd be great if it worked, but it's pretty clear that it doesn't if you go to the tags terfsafe and transandrophobia on tumblr (under "latest" to get the most variety of posters). About 5% of the posters in the terfsafe tag, at an absolute maximum, are marked red, but 30-50% of the posters in the transandrophobia tag are marked red. For reference, transandrophobia is the word used to discuss the unique oppression, discrimination, and experiences that trans men and transmasculine folks face.

I didn't think to check intersex tags, but I've noticed quite a few intersex people I follow are also marked red despite there being absolutely nothing warranting it on their blogs.

So disappointed.

Not a trans person myself, but this used to be a good litmus test especially when posting in spaces with a lot of trans people. But now half of the red accounts I see are just trans people getting friendly fired over nothing. Pretty much pointless now.

it used to be fine, but nowadays it marks trans men and nonbinary people with red more frequently than transphobes, as well as trans women who speak up on the behalf of trans men and nonbinary people. You're better off avoiding shinigami eyes altogether.

I've used this extension for many years as a trans woman always on the lookout for who might not be so friendly towards people like me, and for a while it was pretty good.

That's all changed dramatically within the last year. I began recently to notice just how many pages and people and websites were obviously false-flagged as transphobic by the extension, despite clear and overwhelming support for non-cis identities and no record of transphobia to be found. Even the LGBTQIA+ wiki and Pride Flag wiki were being flagged.

And that's when I learned that its creator is a transmedicalist who hates trans men, intersex people, neopronoun users, and people with nonhuman identities, and has been completely on board with its abuse by people with similar bigotries.

I can only conclude that this extension is now totally unreliable for its stated purpose, and now strongly discourage its use by anyone who's looking to actually curate their spaces.

What an absolute waste of what was once a good thing.

Enshittified and abused to the point that it is no longer fit for purpose.

this USED to be a good addon and genuinely marked only terfs as red. nowadays it marks literally any transmasc, intersex, or nonbinary person as red for existing and being proud. transfems are also marked red if they post anything about supporting ALL trans people. this addon is FOR terfs at this point 👎

This app is decent but sometimes is used as a bludgeon by terfs marking the average trans/enby poc red. I won't say to uninstall it but do not implicitly believe that every marking it's ever made is true and unbiased. Sorry, but you're still going to have to do your homework if you want to know if someone is transphobic or not.

Does not work as it claims to. I've seen multiple radfem and well known terf accounts marked green, and vocally pro queer and trans friendly accounts marked red.

Incorrectly marks trans men, nonbinary people and intersex people as anti-trans in a way that can only be malicious

White transfems can say the most vile transphobic stuff ever and still be marked green, but any poc that's enby/transmasc/2spirit/intersex and calls them out for it gets marked red. Mhm. Uninstalled.

This extension used to be really useful but I've seen multiple trans people who are outspoken advocates for equality get marked red. I think this is becoming more and more easy to abuse. It also seems like specific to Tumblr there is this thing where trans men and nonbinary people specifically are getting marked red which makes me feel really confused and a bit unsafe??? I'll be uninstalling. This is why we can't have nice things...

edit: It also seems like POC are being targeted. Triple, quadruple yikes.

keep seeing intersex people and people who say that trans men face oppression marked red and people who are honest to god using 'theyfab' marked green. useless at this point

im far more likely to run into someone marked red who just happens to be not white, a trans man, intersex, or a combination of the 3 than an actual transphobe

It's been showing more and more bias against trans people who talk about trans masc, nb, and intersex issues (probably more tbh) for years now, but it's getting so bad that I assume a Tumblr blog marked red speaks up for those groups rather than assuming they're a transphobe. I've been keeping it anyway to help me remember which news sites suck, but it's become a detriment. This could have been a good tool, but I guess the mods, or the creator, or both have decided to use it in bad faith against their own community.

The users have bias against trans men, intersex people, and people of color. You have to experience your gender in a way that is "correct" to white transfemmes or else you get marked red.

what even happened here????

"If it sounds too good to be true.": The description claims to target "transphobic/anti-LGBT" content, but it doesn't. Nonbinary, intersex, trans masc, and POC are consistently flagged red. It flags binary white trans women as green, even as they call for the deaths of the aforementioned groups. This is a racist, intersexist, enbyphobic addon. If you identify with any of these groups move on.

yeah this has gone to shit.

I really loved this extension, especially when it came to people who might dog whistle their transphobia. But I've increasingly seen friends/people I follow who are either trans themselves (which, of coure, transphobic trans people exist, but this isn't the case here) or are ally's who get marked as red. This is genuinely heartbreaking, as this extension is something I've been using for years, and it was one of the extension I kept when I moved from Chrome to Firefox. But the lack of updates, and the fact that transphobes can use it against its purposes really sucks. I hope that the devs or someone else can pick up the pieces, but I think I'll uninstall this now.

It's gotten worse over the years. With the amount of false flags it has now it's worse than useless, it's actively harmful to trans people.

The 5-star reviewers are primarily TERFs, just an FYI.

Anyways, yes, this extention USED to be a valuable tool for rooting out harmful people, but nowadays it has become weaponized by TERFs to belittle, ostracize, and invalidate large portions of the queer community.
False flags are pinned against trans men, transmasculine, intersex, nonbinary, and queer people, as well as people of color. They are marked red simply for speaking about the oppression they face and their own experiences, meanwhile TERFs who openly call for the deaths, detransitioning, and rape of transmasculine people remain green, "safe." Tell me- how that is fair? How can someone like that be a safe and trustworthy person in the queer community?

This is not, and never has been, a tool to "call out misogyny." It is an outdated, jumbled mess of code that TERFs are using to make lists of people that don't agree with them. Don't use this addon.

Used to be phenomenal, then slowly over time became utterly useless. People whom I followed on social media became marked as red for speaking out against transphobia, whilst people marked green spouted hate. Unbelievably un-moderated and a useless extension in 2025.

As it is now, it's very flawed. Many people are falsely marked as transphobic constantly.

despite what the devs may say, the extension is pro-radfem and anti-trans; trans men, transmascs, and nonbinary people are marked as transphobic for existing and fighting against bigotry. not even the transfems and trans women it seems to be oriented to are safe; if they don't follow the radfem thinking line, even they will get marked red.
