Even with bots, there is still a person behind them. Someone has to run it, even if a bot is doing all of the work. It would be up to that person to deal with the spammers in their campaigns.
Believe me; as much as I'd like to believe that, YoBit is absolutely terrible at that and no matter how much to complain to them, they won't budge. I think hilariousandco sent them a PM and they ignored it.
