Instead you could run analysis on the voting data from the blockchain database to detect suspicious patterns: both voting and sbd transfers. You could make a bot that then comments when further actions of the same sort are made and 'shame them' into better behaviour.
Yup it sounds good and legit.
this is perfect idea
I'm sorry I don't understand what you are talking about; would you please elaborate further?
Describe in more detail?
