Them being late is not a scam, no one here is getting scammed. I've been in this campaign for a year and always been paid. Sure they are late, and if that concerns you then find another one and stop complaining, no one cares to hear you whine about it. Last payment I received was 6/29, so chill the F out about it already or leave.
I think the last payment was from the week of 12
th June!
I have also been in this campaign for a year, they are abnormally late now and we are usually paid at a similar time to Bitvest (which is what is fairly confusing)!
You are right though, there isn't really much point in complaining as they aren't scamming anyone, they are just slightly late on the payments!
