Answer is simple and obvious: to fill up the signature quota. This is the only forum where you have actual incentive to shitpots and answer to shitposts, so of course even high ranking member will do that (and those are usually in the signature campaigns, therefore having even more incentive than a Newbie/Jr Member). It's the same reason why trolls are so successful here, as people have incentive to engage in pointless discussions.


Those two examples sums up Offtopic nicely. It is a cesspool and even if you make an interesting topic Movie topic for example), it will attract low quality posters who just wants to dump their post to increase activity or eventually those that are in signature campaigns that counts posts written there. I have a feeling that mods simply gave up on that (despite having "No low quality posts and topics rule", similar to altcoin/bounty section. I was somewhat active there when I joined forum, but I gave up eventually.
