I never trusted the bounty management company! All the bounty tasks I did were obtained on this official ANN in BBS! But some officials change the rules for one reason or another! It feels just like a liar!
I think the bounty companies are very reputable and deserve to be trusted. Like amazix, they are not scam. Their rules are very difficult and the check results are the same. But I have never been excluded from their campaign because I do well. And their bounty is amazing
