Sorry if this has already been answered but I was thinking of the point system for the posting. Do making threads count as the maximum credit for a post? I feel the logic behind it is that when you start a thread, it's pretty much guaranteed more views than a post on a thread. It would be pretty hard to abuse considering it's difficult to create a thread without reason or in other words "just for the free BTC". Plus, why would anyone go out there way to create a thread when they could substitute it with a post in the gambling section with ease. In essence, you compensate someone posting a thread for doing greater amounts of advertising.
Not a bad idea. I've made threads that got up to 3,000+ views. I doubt any of my replies got anywhere near this many views. Although there would be the risk of people posting spammy threads and cluttering up the boards but I guess that's a possibility even today.
That is the only downside. But it would be hard to have spammish threads without being obvious. If someone's goal was to spam and squeeze out every ounce of BTC from the campaign, they would more than likely spam the higher point value sections rather than create new topics so it would be more beneficial to those who create topics every now and then so valid reasons.
