Unrealistic pay rate. All rank same rate isn't wise decision. All user experiences isn't same. However its depend on you how are you going to pay participants, we can't make comment about it.
So why are you commenting about it ? lol
It's so fuckin impossible to keep everyone happy at the same time. First, spam was the problem and now everyone is whining about the pay-rates. No one is forcing you to join the campaign if you don't like the rates or the rules move on. I like the new rules but the 100 minimum count should probably go away as that is not a clear indication of a good post.
