This thing is getting a lot of bad reviews due to the concept of "men benefit from misogyny" paired with "trans men are, in fact, men" causing them to hold systemic power over trans women despite both experiencing transphobia. The way that trans women experience both misogyny and transphobia yields the unique combination known as transmisogyny, basic intersectionality stuff, and this tool being used to mark transmisogynists who despite ostensibly being good on "trans issues" participate in transmisogynistic posting etc has gotten non-transfem people invested in their own perception of inculpability up in arms.

Works well. I always take it with a grain of salt (always checking the person marked). I've used the extension for many years, and have only found a handful of instances where it was obvious as a miss-flag, otherwise seemed pretty accurate. The creator does kinda suck though. Though I don't use Tumblr, so that might be why it's been fairly fine for me. I've heard that it can be pretty hit or miss there as people use it against each other.

A lot of people are rating this 1 star because they are being correctly flagged as transmisogynists. Shinigami Eyes is working as intended, and they're big mad about it.

Not something to follow religiously, but does a pretty decent job of letting you know when to take extra caution around certain accounts.

Unfortunately it's currently getting review-bombed becuase a very small number of tumblr transmasc/intersex people got flagged red after repeatedly saying anti-transfem things, and so have been trying to convince everyone the extension has an agenda against them all. I've found it to be pretty accurate though.

this extension is an excellent flag that signals to me that i need to dig deeper into a person's stances on trans people before sharing their content online. contrary to many of these reviews, the moderation is extremely consistent; it is simply that whoever's doing the moderation is focused on preventing transmisogyny (as they should be). the website itself states, "Don't assume someone is not transphobic just because they are trans or non-binary themselves." every single trans person i've seen marked red on shinigami eyes or complaining about a false flag has indeed had transmisogynistic rhetoric on their blog. this extension isn't wrongfully marking anyone; you simply disagree with the moderator(s) when it comes to what is or isn't transphobic. personally, this extension has helped me block terfs i see in my notifications so that my posts don't gain traction in their circles, which has been massively useful over the years. thank you shinigami eyes!

has its uses, got recommended by this really cool cis dude. it's always a delight to stumble upon a celebrity marked green when i least expect it. no clue what the recent enmity's about, this thang makes the web a little less scary......

One star reviewers are mad that their transmisogyny is being highlighted. Would advise you to ignore them if you are a serious person. This is a very useful extension that I refuse to go without in my browser.

genuinely good extension that has had a smear campaign against it. primarily by those who would like to pretend that being transgender makes one immune to being transphobic when it's in the extension's guidelines to "not to treat people differently just because of their gender, age or orientation"

these people can fully believe that trans women can be transphobic because "transandrophobia". but cannot fathom that they themselves can platform transphobic ideals.

overall great extension, even if you're not trying to block transandrophobia truthers as it accurately hits radfems pretty well

I'm a trans woman, this add-on has been excellent at letting me know who's safe and who isn't. All the complaints about "false" markings, and yet I've never come across a false marking yet. This tool is primary a way of marking transmisogynists, and if you're marked red and/or mad about this extension... you need to take a deep reflection of yourself rather than continuing to show your hatred of women sharing their experiences and trying to stay safe. Thank you to the developers and to all my sisters!

the people complaining about "false flags" are simply mad they can't get away with transmisogyny on the basis of also being trans anymore.

A wonder extension! Never been wrong.

This extension works perfectly; I have yet to see someone be marked incorrectly by it. Many people who get marked red get pissy about it and claim to be "incorrectly" marked red, but I have yet to see one who actually treats transgender women with a modicum of respect.
