Perhaps we are looking at it the wrong way. Ban the campaign managers and the projects that hire them if they use people who are using spam bots and give everyone in the campaign a warning that they were working with spammers. After a certain number of warnings you would get a ban. Would that be too harsh?

Seriously, I use the altcoin section for a few things and would not be put at all if it went away, so it might be a harsh point of view, but to me it looks like most of the bounty campaigns are a lot crappier then they used to be.
