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.
What is the meaning of the third world? If you can't give a reasonable explanation, then I think you have racial discrimination in this sentence. A racially discriminating person, I think even have received higher education, it is only a kind of garbage. Such remarks are disgusting.
