People don’t pay to be on a forum. People may to be in a private club (not the type we’re thinking here now) of some sort, by set a price tag on opening any account and the forum is done for.

Were campaigns to be controlled and regulated by the forum, it could be theoretically something to ponder, in order to monetarize part of the business (i.e. free account would not allow one to participate in campaigns, paid account would). The easy way around would be to make Copper Membership mandatory to participate in campaigns. But … the forum intake is not to regulate how campaigns are run, not benefit from them more than through the forum Ads.

Now if people cheat the system (i.e. multiple accounts participating in the same campaign), then it probably goes to show that the manager is mostly centred in quantity rather than in quality, and probably doesn’t really mind that much). Set higher quality standards, and the will to have more than one participating account will wither, plus the posting style would likely get spotted. If a campaign is all about posting and reposting simple Tweets and Facebook nullities, then that’s what you get.
