Some years ago, Pussy Riot put out information on how to use Makeup to confound face detection algorithms.
On an unrelated note: This is probably going to be blocked in ML because I used the word "pussy". I wonder why that instance has a problem with me mentioning that word. Could it be perhaps the name of a feminist anarchist group activity resisting domestic Russian oppression? No, I'm sure that's a coincidence.
Edit: Ty to everyone who helped correct my misunderstanding. The feedback has been informative, but I'll leave my comment as-is so people reading have context incase they also have misconceptions.
AFAIK .ml doesn’t automatically block comments from other instances containing slurs, they only automatically block slurs from being posted by their own users.
What if a farmer wants to join the instance and comments about waking up to the cock singing, finding the bitches in heat and gathering faggots from the yard
