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".

this extension has been hijacked by racists, transandrophobes, intersexists, and exorsexists to wrongfully mark anyone who doesn't agree with their white-centric and bioessentialist views as transphobes

I'm transfem. I avoid discourse and argumentative posts on tumblr for my own mental health, and I made a side blog to uplift trans, nonbinary, and intersex folks: mutual aid, fun memes, positivity/reassurances, guides/tips for transition, and so on. I stayed in my lane and wanted to make people happy with my little zen garden of a blog.

My blog then got marked as red and I started getting non-stop harassment and doxxing in my asks and messages. I received messages telling me I was a danger to trans women, that I was faking my gender and that I'm secretly a "filthy theyfab tme MRA", that I was a psyop infiltrating the community, and so on. And of course, plenty of death threats, suicide bait, and slurs that I cannot in good conscience list here.

The reason? Because I had been reblogging posts uplifting transmascs and intersex people. I even responded to some of the asks stating where I even posted anything that could be seen as remotely harmful to trans women, and the *only* response I ever got was linking to a post saying "love your local trans men". That was it. That was the only 'proof' I ever got. After years of running that positivity blog, it was me sharing a post saying trans men deserve love that got me marked as red. I was forced to deactivate. And now I'm glad I never linked my main account to that alt account of mine, or else I'd probably have lost that one too. All because I, a transfem, wanted to show some love to my other trans siblings.

From time to time, I'll see screenshots of tumblr users who have been marked green with this plugin. Users that I have seen say the most vile transphobic and intersexist stuff ever (and also, often, pretty blatantly racist too, but that's not the scope of this plugin). And yet these people are marked green, despite their blogs being full of BLATANT transphobia against anyone who isn't transfem (and the "right" kind of transfem, as I can personally attest to now).

So to the users marking this 5 stars defensively, saying "ummm maybe you wouldn't be marked red if you cared about transfems :) after all this plugin is for us, not for you :) you're all just terfs who are mad at us for wanting to be safe :)"

Yeah, I guess so. I guess this plugin *is* for you, now. It used to be for all trans people, for marking transphobia of any kind, no matter what. Now the devs have rewritten the rules to exclude certain anti-transmasc slurs as being considered transphobic, constantly mark transmascs, enbies, and intersex folks as red for just existing, and let actual bigots run around rampant with a lil green box around their name. Transfems that uplift their transmasc siblings, even if they don't engage in the discourse, get marked as red and chased out of the community.

This plugin, way back in the day, used to simply mark transphobes. A flawed system, perhaps (having a plugin that simply shows 'good' or 'bad' people is going to be abused in some way), but I can't say the goal wasn't noble. Now when I see a screenshot of a tumblr user and they're marked green, I check their blog, and 80% of the time they're engaging in harassment against anyone who isn't in their little circle of trans radfems. And I do not say 'radfem' lightly -- I'm seeing actual radfem rhetoric being used to silence anyone they think is the 'enemy' to them. It is a disgusting reversal. Y'all literally harassed punkitt for MONTHS for saying basic, tame, milquetoast shit like "Hey maybe being mean to trans men is wrong, actually", because you've become so steeped in this ridiculous infighting discourse. And this plugin is just the right hand of the law to you.

So thanks, shinigami eyes and the fanatics that support it: you've made an infighting tool that lets you destroy anyone you want by marking them red for the pettiest reasons ever. You've made a plugin that allows you to ostracize whichever queer people personally piss you off.

"Safe for transfems" my ass.

Signed, a transfem that y'all decided to make un-safe.

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.
