Yes, we have asked him(cryptodevil) to remove negative comments, but this maniac user(cryptodevil) replied more abusive comments then his negative comments.
If he doesn't want to remove it, then there is nothing that moderators can do. Moderators don't moderate trust, especially when they haven't been active for two months. 
If you want to stop cryptodevil's trust affecting your score by default, the only things you can do is persuade him to remove it or contact dooglus to remove him from the Default Trust system. I wouldn't hold your breath for either of those happening though.
Else if you want the admins to interfere move your topic to ''meta'' (Bitcoin Forum > Other > Meta)
If something is to do with a user's Reputation, then it gets moved to the Reputation board. He is only asking for admin intervention because he does not understand how the DT system works.My vote is also for megacrypton. mod ban user- cryptodevil and restore trust of megacrypton profile
My vote is also for megacrypton. i just reviewed cryptodevil profile, that user only put negative comments on every members profile, NO Proof, No Proper ref. my vote is also to ban cryptodevil user
Your obvious shill accounts isn't helping your case at all, I hope you know.
