Oh, I just realized that I haven't saw their signatures for a while and that their previous campaign was closed. I agree with others that they barely can attract good posters with such low payment rates. Especially if you're in their lower tier. But where did you get that you can earn up to $40 week? I see that in tier A they pay 3500 Satoshi per post, it's almot $1 and if you will make 60 posts, you can earn $60.
But the manager will keep an eye out for low-quality posters and the manager had said so after the announcement of the accepted participants.
Tier A started with a rates of 2200 sat and has now been increased to 3500 sat.
That's much better than before.
