They have a very long bounty campaign and they cheat their participants, it's like adding insult to injury, and their bounty manager does not have a good reputation also he is involved in two fraud campaign, better check the reputation of the campaign you are joining.
I have PM the manager because there is a similar situation with a recently concluded campaign he handled called kalc. This is pure shortchange and it is no longer a mistake when it seems to be reoccurring with different campaigns managed by the same person.
