this thread should be accompanied by polling so that the results are more visible.  Well, I really like bounty managers who work professionally, systematically, neatly, thoroughly and committed to eliminating fraud.  I have never joined a bounty from BM mentioned by OP, it seems worth a try.  I often join the bounty from Sylon, unfortunately, at this time, there is nothing new.  I also like joining bounties from Arteezy, Jolin and Julerz.  They are very thorough in eliminating cheaters.
