Whats the weirdest thing you came across on AO3?

Once I was reading fanfiction for the couple Neil and Andrew from the book series all for the game, Andrew backstory is that he was raped as a child so when i read fanfiction for this specific couple i don't exclude the rape and underage tags since usually people use it when they're expanding on his backstory but obviously this one time it was a mistake cuz this person straight up wrote Andrew as someone addict to csam because the author themselves were addicted to it it was the first time I saw someone get hate on AO3
