I think a good compromise would be to place them on a list to be manually reviewed by humans. I’ve seen those brigades so I think you make a great point.
The mentality of “I haven’t seen it so it must be that it doesn’t exist” on some of the replies here is weird.

I really don’t think the firefish admin “has no issues with racism”. The “evidence” there is that Kainoa (the admin) boosted a link to an Electric Frontier Foundation page sent by Eris. I think that’s a ridiculous conclusion to make.

I think it’s too hasty of a conclusion to say they were doctored, at least based on what I saw following the situation. There were suspicions/allegations of it, but no clear evidence.
