and the buyer apparently decided to leave hive instead of, you know, stop buying votes
that's typical, but they will not leave or either come back with a new account/token, just a matter of time, when you taste the cake it's good to keep eating
as for the rest i think it's fair, you give the rewards it's more than right to check how these rewards are distributed then, it's not excessive control... if they don't like it there is something to hide...in the end giving to leaders is a sign of faith in them already
