Trolls get culled by moderators quite quickly in /vt/, and most of the threads are actual fan-threads so shitposters are often just completely ignored.
There was a case a few days ago where a shitposter was flinging garbage everywhere in one of the individual Holo threads and he was completely ignored. Someone eventually started arguing with him and it went on for a fair while before the entire series of posts disappeared at the same time with only 1 ban appearing. Literally arguing with himself in order to shit up a thread.
These people are here now instead.
