Wow, that looks extremely blatant. Having a look in the thread there appears to be more disgruntled users than yourself. I simply wanted to thank you for bringing this to attention as it encourages me to use proper diligence (as much as is possible) when participating in bounty campaigns in the future, although I was (fortunately) not a part of this one. Surely others will be encouraged similarly. Even benign bounty campaigns are not immune from cheaters..
