Trust is not "moderated." The only way that you can get the negative trust removed is to convince Vod to remove it. Please note that AFAIK, insulting Vod is not going to help your slim chances of getting him to remove it. Also, if you attempt to invoke "countermeasures" such as leaving him fake bad trust or making legal threats, that strategy won't work either. I don't think kissing his ass will work either, though....
Oh threatening ? Why? This is how it works? I hope not.
Regarding saying my personal opinion I don't that's something wrong, he just proved to me in 2 months of bitcointalk that he has no use of his brain most of the time and just a big ego.
Very sad to hear that trust is not moderated.
