Why do yurishits keep crossboarding so hard when given their own board? There are often many posts that talk about 'trolling' /a/ and getting reactions. They talk about how they push yuri in /a/ and make bait threads.

They are everywhere on /a/ nowadays. Most of the time they push liberal progressive values in anime and faggotry. Its ruining anime culture.

Why do they do this instead of staying on their own board?
