Nobody seems to be considering the possibility that they are not actually paying campaign participants, but one or two so-called "bumping" services, and that all participant accounts are actually alts belonging to the same group.
I actually thought about this before, but learnt that 1xbit is actually paying many of their participants on a regular basis despite all the scam accusations against them which did surprise me to be honest.
I guess they will continue paying their participants until their goals are achieved in this forum. Some of these participants use alt accounts to scam the scammers themselves.
