Fantastic and reliable. Been using it for years and I've never accounted a mislabelled red name.

The dropping ratings are because some people are very upset that it flags transphobic (particularly transmisogynistic) transgender people as transphobic. If you are a huge fan of men's rights activism and using the phrase "AFAB trans woman" I suppose you won't like this add-on very much.

I do think there's an actual problem with this add-on, and that's its friendly flagging. I constantly see green highlights on the accounts of random trans people who don't even talk about being trans that much, and more importantly on outwardly transphobic or otherwise bigoted (e.g. racist, antisemitic) accounts. I think the friendly flagging system needs review and better filtering. I've come to completely disregard it.

Despite that, the unfriendly flagging is consistent and incredibly thorough. I need to reiterate that in all my years of using this add-on I've never encountered an unfriendly misflag.
