Thanks for you words about my activity as a witness. Won't rejoin the list, because supporting something that I consider abusive would make me hold conflicting views, I'm not into this anymore.

As for downvoting, the current implementation allows for much more abuse than in any game theory. There is no stake in votes, just influence. It would be stake if every vote (up or down) will put some money on the table. I already made a proposal for this, back when I was a witness. https://steemit.com/steemit/@dragosroua/yavap-yet-another-voting-algorithm-proposal-or-what-i-actually-understand-by-proof-o-stake
