This is a reality! Most of people join bounty and these people are uneducated from 3rd world countries. I don't want to be rude, but it is true, because in Europe and America people gain much more on usual job and twitting and posting in social network for some bucks isn't for them.
I can't agree with you because I personally know some American guys who are into bounties as well. Doing bounty campaign is not determinant on where one is from. Let's stop looking down on people from third world countries, they didn't choose that life it choose them. Treat everyone on a human being level and based on their individual displays.
