No, I wouldn't support rolling back to HF18. I would easily support rolling back the whale-power moratorium! I believe that's a bigger root of the problem. Also I think we need to establish some kind of consensus on what constitutes abusive self-voting and police that better.
Actually, I'd support suppressing abusive self-voting before reinstating the whale ban.
Then you may be interested in some work I am doing. 🙂
