Regarding Sugehprasetyo and Nankers, I haven't found any other involvement besides merit trading.
same here, I have a lot of time to track the address which his bounty proof, I can't find anything except merit abuse. I have only 1 proof of their Imgur account which he also used an unreasonable alibi, where he fenced off that account from his friend. but, with the ability how the alt connected to each other, I can't believe that.
and in fact, no defense from him, he already got a negative tag, if not going true he will post the defense.
Nice catch, the fact that the connected accounts are involved in bounty cheating should be more than enough, (at least for me) to leave the alt accounts with some negative tags so that bounty managers looking to enroll them know the kind of person behind the accounts.
he will continue spamming on my local board if the manager accepted him.
I don't have a problem if only 1 but if continue spamming with 3 or 5 alt, I think it's disgusting.
