Reinstalled after a few years to double check some stuff on tumblr and WOW every single flagged blog I found was flagged for the crime of having it/its pronouns in bio. Incredible work devs and reporters, totally what this app was made for.

Used to be a decent add-on, but with little to no moderation, has turned into a means of targeting trans people who do not fit the standards of others, and has become harmful instead to a community it claims to uplift.

It was great a few years ago, but now all it really is good for is encouraging infighting in gender diverse spaces and misflagging transmen as being anti-trans simply because they are men. I'd rather navigate blindly through the internet and block/move on as needed when I find harmful people online than deal with this one any more.

extension marks trans men red all the time because the extension is ran by transmasc hating devs

Not worth it.

This isn't useful anymore, there are too many false positives for it to be helpful. You have to go to each account and individually verify whether they were marked as red/green correctly, which defeats the entire point of the extension.

For example, there are many pro-trans advocates and allies are marked red, despite no wrongdoing, by people with personal grudges against them. And there are transphobic people who are marked green purely on the basis of being trans. Who gets marked as red or green isn't supposed to be dictated by one's identity, or by differing opinions on smaller matters within the LGBT+ community (like disagreements over using neopronouns or micro-labels).

The system is supposed to be: red=unsafe (dangerous transphobic accounts), and green=safe (vocal, proactive supporters of trans rights). Because this extension is being misused and poorly moderated, that system doesn't function anymore.

A lot of trans rights supporters, many of whom are trans themselves, are marked red because they talk positively about intersex people, non-binary people (including non-binary transfemmes and transmascs), trans men, or trans people of color. Many Black trans people specifically are reporting that they've been falsely flagged as red because they critique racial disparities within the broader queer and trans communities; this is an unacceptable misuse of the SE extension to isolate or discredit Black transgender people.

I used to rely on SE to quickly block transphobes like TERFs to keep myself safe online, but these days the TERFs are hardly getting flagged as red at all, and too many times I've checked a red account and realized it's just somebody who discussed intersexism, with no evidence to any instances of transphobia in their account history.

This is wrong and demonstrates biases in the team moderating the extension and the dwindling userbase. This needs to be fixed and the rules clarified (and enforced better by the SE curators) to make this extension safe to use again.

got marked red as a trans woman for asking someone to provide a source regarding interpersonal drama in my city. literally can't make this shit up. used to only mark transphobes, now they mark trans people (and especially masculine trans people) red for petty bullshit. i've been active and vocal for trans rights my entire life. what a joke

I am transfem, and despite this I was marked red by an ex-mutual for petty interpersonal drama, and have been unable to reverse this. I have also seen so many others have similar experiences. I personally believe going into an account or link with your own judgment and eyes is a more consistent and wise thing to do to make your space online feel safest for you.

Largely overrun by weird tumblr trans women who hate anyone AFAB these days. Considering how just being transmasc or thinking pedophilia is bad will get you flagged red.

Immensely racist and transandrophobic. Also loves to defend pedos, for some reason.

I am a gender nonconforming trans individual who is outspoken about my support for queer rights, but I found myself marked red on shinigami eyes after someone I got into a petty online disagreement with had all of their friends to mark me as unsafe. This is an issue I've seen repeat over the last multiple years, and it's only gotten worse with time. This used to be a really useful extension, but it's been warped and weaponized against the very community that built it. I can't say I recommend it anymore because it does not accurately identify transphobia/queerphobia as it used to.

Genuinely does not serve its intended purpose anymore. People that make threats against trans men and transmascs are marked green but anyone who speaks out against anti transmasculinity, exorsexism, or intersexism is marked red. Trans men and transmascs speaking about their experiences and putting a name to that experience isn't a threat to trans women or transfems.

Used to be useful. Infiltrated by TERFs, overrun with racism, exorsexism, and lateral transphobia. Cannot speak for other social media sites as I don't use them, but it's useless on tumblr. It used to be if I saw a red name and checked, nearly 100% of the time it was a TERF/radfem or otherwise transphobe. Now, if I see a red name, nearly 100% of the time it's just a trans masculine person or an intersex person. It seems like he/him in bio is enough to get you marked red on this extension now lmfao. Would not recommend, hope an alternative that seeks to protect ALL trans people is created.

Used to be good until the bis came in

lots of false flags, intersex people and trans men are almost always marked red while transmisandrists are marked green

used to use this religiously after it first came out and at first it was genuinely useful. now after discovering i'm intersex i try to go to any community for the topic anywhere and everyone is marked red because our discussions of gender and sex don't 100% align with the mods views (which then gets called transmisogynist, when nobody is saying anything of the sort at all). this includes a disproportionate number of transfems, so the claims that simply being transfem will get you marked green are false. i have, however, seen people get marked within days of making an account somewhere *just because they are posting in intersex spaces*. so do with that information what you will. i personally never plan on using the extension again, i'll vet people myself

Abysmal tool if you genuinely care about safety from transphobes. There is a mountain of examples where people who spew intersexist, exorsexist and antitransmasculine hatred 24/7 get to secure their "safe" marking while painting their trans siblings who won't stand for that as the real transphobes.

The Wikipedia page for gloves is marked green but only in spanish and asturian, this thing has no moderation whatsoever

It also says a lot that most of the recent 5 stars reviews are "you're just mad you're transmisogynistic and got flagged red LOL!" but never address the racism and the transphobes being flagged green complaints that they're responding to

I've also just noticed that the website got updated since when I first installed this addon and lists "theyfab" as a "community infighting" term when I've only ever heard it being said by TERFs. It's an enbyphobic slur and it's clearly transphobic

This extension- as many others have already pointed out- is no longer accurate or curated in any shape or form. I've used it for many years now, and I just keep catching false flags, especially on tumblr. Not worth the download in 2026
