It used to be very useful but it's gone way downhill. Transman and intersex people have been marked red, completely untrustworthy now.

Absolute mess as of late, and incredibly disappointing. Do NOT use this tool; it's unreliable at best, and at worst, actively dangerous.

Trans men, intersex people and nonbinary folks existing isn't transphobic, nor are the people supporting them and discussing the problems and discrimination these people face. Feminism-appropriating transphobes are. Stop marking the former as anti-trans and the latter pro-trans when we all know neither is true.

Shinigami Eyes has been useful in the past, but in the last year or so has really shit the bed. Started with actively transphobic individuals being marked as green, trans friendly people that simply talked about a trans person's bad behaviour being marked red, & then quickly started marking actual trans & intersex people as red, especially when they're masculine.

Being a man is not transphobic. Trans men talking about their unique oppression is not transphobic. Being intersex is not transphobic. Being nonbinary is not transphobic. Acknowledging a trans individual's harmful actions is not transphobic.

Why the trans community is suddenly adopting transphobic beliefs is beyond me & I'm incredibly disappointed. If you genuinely believe perisex trans women are the only people allowed to talk about trans issues you need to dig deep & consider why. Do you actually want equality, or do you just want a turn at being on top?

Many users have mentioned there is a bias against transmasculine and intersex individuals and marking them anti-trans, which is true. But I'd like to also add that I've seen literal trans exclusionary radical feminists marked green, and trans women marked as red.

In concept I appreciated what this addon was going for, but past using it for news sources (which with recent events I find it hard to trust anymore) it's useless.

Used to be a very helpful extension for identifying TERFs, but personal biases have made this extension unreliable for its intended purpose.

Inaccurate description - Transmen and Intersex individuals are tagged as transphobic often. As well as anyone who is supportive of transmen and intersex people. Do not use without being ready to research EVERY color change.

You claim to stand for trans people and yet you peddle the very lies and hatred towards transmasc/intersex people that others hurl at us. You are a traitor to your own people. You have shown me that there is no LGBT community- only communities of people who are LGBT. The hatred and lies you spew are disgusting and dangerous. You are using this as add on as a tool to spread your vitriol and I will not stand for that.

This extension really fell off in the past year. In addition to marking intersex and trans masc people who are not transphobic as being anti-trans, I've noticed actual transphobic accounts being marked as pro-trans? For a while I thought maybe they were just automatically approving accounts that were mass-marked, but after recent discoveries it seems that the devs and mods are just using the extension to mark people they like and don't like. I'm not interested in your personal biases and who is or isn't invited to your tea party, I just want to block actual TERFs and transphobes. Don't use this, it's just another tool that's been twisted to promote community in-fighting.

(this review was written in may 2026)

it's been a while since i removed the extension due to the many many allegations, so i decided to try it out again, see if it's back to being useful.

i scrolled through maybe a hundred blogs, and of the dozens of red marked blogs, ONE was a terf and almost half of the red blogs were explicitly pro trans

of the dozens of green marked blogs, most were pro trans, but there were TWO terfs

of the unmarked rest, several more terfs, but maybe people havent gotten around to it, dont worry i marked all the ones i encountered to correct this.

how were there more green terfs than red ones? why were so many pro trans blogs being marked red?

this is an unacceptable failure rate, the program no longer fulfills its stated goals at least on tumblr, and since there has been no effort in the 18 months since i stopped using it to remedy this i can only conclude the purpose of it is what it does, and what it does is mark pro transmasc pro black and pro intersex blogs as trans unfriendly, while marking anti trans blogs as trans friendly or leaving them unmarked

trans men do face specific oppression for being trans men. that does not necessitate that "misandry" as a whole exists, as trans men are not one-to-one with cis men. said oppression is generally based in misogyny, actually. unfortunately, the creators of this app have decided that people who acknowledge this are transphobic/transmisogynistic.

you all have the chance to apologize to your fellow trans people and make this right! there are absolutely transphobic trans people, i'm not disputing that. but you all seem to be very choosy as to what qualifies for that. for example, calling someone "theyfab" is innately transphobic, yet that is allowed to slip by. i've marked transmisogynistic trans men and anti-transmasculine trans women, and only the former stays red universally. stop having double standards, y'all.

originally started off as a great tool to help identify terfs, radfems, and other conservatives, but recently, people who have been standing up for intersex and transmasc rights and talking about their oppression have resulted in very trans-friendly people being marked as red. unreliable at best and downright dangerous at worst. do better

no longer trustworthy. people marked trans-positive will say / post blatant transphobic rhetoric as well as attacking other trans people openly. don't get this.

Works pretty good! It's easy to use and readable at a glance without being too obtrusive or ugly looking. The multiple color options are great too!

I don't really know what all these other reviews are talking about when they say that transmascs and nonbinary people and intersex people are being marked unfairly, I haven't personally experienced that or seen evidence of intentional malice on the part of the developer or anyone moderating reports. A lot of these reviews focus heavily on transmascs being targeted specifically, but I'm transmasc, and I follow a lot of transmascs and none of the people I follow are red "just for being transmasc"

If you're reading this and you've experienced people being marked as anti-trans when you think they should be trans friendly, or vice versa, you can remark them! You right click with the mouse and then mark them how you think they should be marked! The community itself is the one marking things, so sometimes it does get it wrong

Judging by how some of the people leaving the reviews or posting about it talk though....... maybe it's just working as intended... ._.

Used to be useful for filtering out TERFs. Shinigami Eyes is useless now since the mods are blatantly against intersex people, and abuse their power against vulnerable community members. Not trustworthy.

Devs went off the rails and have started marking intersex people and activists as "transphobic." Very disappointing.

ironically enough became transphobic

To make an extension that has been seen as a way to keep the trans and LGBTQ+ community safe, only to then weaponize this to attack and demonize transmascs, intersex people, and poc, is frankly disappointing and worth condemning. We should be seeking trans unity, and this extension is no longer reliable to achieve such.

Has become increasingly unreliable as the devs have started marking profiles of intersex people as "transphobic", even when they have expressed support for the trans community.

has started targeting transmascs/enbies and pro-autonomy intersex mentions as red. no longer trustworthy
