I don't think "proper regulation" ever works. As soon as there are clear rules, they will be exploited by those who are okay with doing so, and that's the problem. We will only ever have as much freedom as the amount of cooperation we create. Inhibiting vote selling or bit-bots is not actually possible.

Perhaps. But I'm thinking about identify them first, then there'll be many ways to deal with it.
Then you should be downvoting this post with the rest of us!
