What is something someone can gain by swarming an instance or forums like yours with bots? I cant wrap my head around it. Also if someone has an instance and swarms it with bot accounts, it may seem like you got a popular instance but where is the revenue if there are noone who is able to click an ad? Do they do it just for the lols?
I have some tiny bit of doubts left but at least it does sound like one possible reason for people swarming servers with bots
