Most forums have a TOS/TOU that you agree to when you sign up for the forum. In many cases commercial members are held to a higher standard than the general populace. I moderate on a very large forum and we have about 2% of the people that "don't get it". FWIW on that one questioning moderators' decisions in public can get you banned. People quite often forget that forums are privately owned and the owner sets the rules. Also the moderation staff is typically all volunteer and they are human.

In this case I would inquire as to what the exact issue is. On the forum I moderate it takes a staff consensus prior to any real action. There are a few notable exceptions where an individual moderator can pull an offending post, but then it is followed up by a team effort. From what I have seen here on BF a similar system is used.

I have purchased parts from Thor and he has been helpful on the newer Dahon's. IMHO Dahon itself is quite often the problem.
