People are using bots in these sections. I've seen people using bots with blatantly obvious hacked accounts to copy and paste somebody else details from earlier in the thread in Games and Rounds. They obviously don't care about the giveaway but just want to rank up their accounts with absolutely no effort on their part.

As mprep indicated above I have previously suggested we remove boards like Bounties and Games and Rounds from counting towards post count and activity because those boards are just being massively abused to farm accounts en mass and posts in there contribute absolutely nothing.  If they were removed then a lot of people just wouldn't even bother.
