Most users don't even read the posts they are replying too,  so I think it is possible that some of those people who applied didn't make any kind of research before applying, just looked at the payment and applied.

Of course, they are doing this on their own risk of getting tagged or damaging their reputation.

Also, as Hhampuz, a reputable manager, was managing the campaign before, and he gives the campaign credibility (even for the new one). Few people ever read Reputation board, so they probably do not know what happened.

A user could have been rejected by Hhampuz, and he saw an opportunity to join now this new campaign.
