I'm thinking of making Games & Rounds not count toward posts or activity. What other boards would be good candidates for this? Maybe Off-topic, though some decent discussions occur there, so I'm not sure about that.
When you say activity does that include post count as well? If so, Games and Rounds for sure. I was actually going to suggest we prohibit forum-based giveaways like we did with the alt coin section but this would be better. I would also vote for Off topic. Can't remember the last time I saw a decent discussion taking place in there but even good threads can quickly get swamped and taken over by spammers but this might actually improve discussion since spammers/farmers will hopefully leave it alone.
Why prohibit giveaways? I don't think the giveaway threads should be considered spammy as users posts their bitcoin addresses to get tipped and some giveaway threads have discussions going on as well like Stunna's threads. That way even Auction and Lending sections have users just posting the template for loans/bids. It makes these sections also similar.
