Did you send a message to Satofan before creating this thread and try to resolve the situation without escalation? If not, you might consider doing that now. Ultimately it's a neutral trust so it's not a huge deal since neutral trust doesn't really hurt anyone. You're going to see conflicting opinions as far as whether  a user can basically post their opinion in the form of a neutral trust on your profile. Some are for and some are against. Some will tell you to get "thicker skin"  and move on.

I suggest that if you disagree with his opinion and you guys cannot come to a mutual agreement that you ignore him and if you need to ~ him on your trust list.
