One of my favourite things to see is the shipper/fujo/yume fandom have infighting. Fujos and yumes gladly shit on waifufags but have to be wary of shippers.
There was a BL gacha that had a hilarious drama where it was doing very well, and then they had an event where the MC's love interests fucked each other, and 2 months later the game EOSd. Shippers are confused and mad why all the fujos left.
