I hadn't noticed the user in question doing what he did because I think he posts mainly in the gambling section (correct me if I'm wrong; I'm too lazy to check), which I stay away from unless I'm doing post reviews for people.
I'm even pretty sure he's still at it on June 13 based on a post archive where he just cites a number of posts without adding anything and comes back to edit them after a few hours or maybe a different day. I think this kind of behavior is not tolerated as right behavior in the campaign, he wants payment but not doing things the right way.
The campaign manager is responsible for checking this kind of behavior, and I think he will do it more strictly now for all his participants.
