There was already a culture of "roleplaying as idolfags" there and when vtubers started to get big in the late 2010s that culture was added to the vtuber threads. This then got turbocharged by young normalfags, ESLs, and crossboarders discovering vtubers and thinking this was normal behavior. /vt/'s creation was the final nail in the coffin, as you now have an entire board for vtubers where the /jp/ culture of being a shitposting retard is considered normal.
