To minimize this risk, I don't put too much effort in this. I do blog bounty in my own blog, so I attract visitors, even if I'm not paid. A signature campaign, is also, good, because I post here anyway. We post here to exchange knowledge, with people who have similar interest. This is the nice thing about forums. I'm an old internet user, from the times of usenet, where we participate exactly for this. Today, social media, is a hunt for followers, and I'm not interested in that. This is one of the best forums, that I have ever participated, so it's fun to be here. If my signature bounty pays, well, this is an extra.
