I had no idea it worked like that either. Apparently, the issuing account would simply need to mute each specific user that was breaking the "rules" or "guidelines".
I wouldn't have set the rewards to go 99% to stake if I hadn't accidentally configured INT to unstake completely in 7 days. Since that is the case, it makes sense to stake as much as possible and if someone wants to dump all of it they only have to wait a week.
