Maybe I'm just being paranoid, cynical, skeptical, or (most likely,) a combination of all three, but it's almost like they planned for red-tagged sockpuppets to make up the majority of applicants. Makes you wonder if there's any affiliation between the folks behind AdkinsBET and 1xbit.
Then I'm being paranoid to thinking they are allowing those accounts to participate in the campaign just as a cover-up as those accounts are actually used by the same people who run the website and there is no real payment going on there but once the week is over they can claim look, we have paid more than 3000$ or whatever in signature earnings, we're legit!!!!! And actually, I don't see this as a possibility rather I wonder why would anyone think this is not what's happening!
As for the payments for the reviews, I was pretty sure they were going to pay, it was clearly a promo move to gain trust if possible or at least have some comeback on the people accusing them of being scammers, they spend what, like 300$ on all this for those and just one 0.1 BTC from a gullible user that sees them throwing money around would make up for all the costs.
