Payment amount has been lowered decently due to extremely high demand, sorry for any inconvenience.
Well put it this way guys, Stunna is still offering the best sig campaign in terms of BTC per post made and it is technically free money. It's not surprising that Stunna would move to become closer to the values of other campaigns seeing as there really aren't any competitors still willing to pay so much.
Unlikely as it may seem, maybe this guy will actually pay out on the 25th of this month:
