Well, we have the FAQs, and you check off before registering that you have read and understood them.
This is a privately owned site, and those are the rules that Mirko wants the mods to use. It is not a democracy as some seem to think. We do not have a court system. If you have a question on an infraction that you have been given, or ban, etc...then by all means PM the mod, PM an admin. etc...we have had infractions, bans, etc...over turned. I have had those discussions quite often at times. If there is a question, we bring it to the mods and we discuss. The decision has been given to us to make by Mirko, the owner of this site. Therefore we make the final decisions. We have put in place a system that gives plenty of chances. Unless of course it is very evident that the person is a troll, and those are actually pretty easy to catch and take care of.
In fact, I had a poster just a few weeks ago ask me to bring his questions on his probationary ban to the mods. I made a thread in the mod room, and it was discussed.
Having a forum on it, brings in people that really its no business of theirs what the specifics of the issue is, other than what is seen on the thread and posts in question. It is between the poster and the body that has been given the job of making the decisions by the owner of this site.
There is no way to make a rule for every situation, that is impossible, and it won't happen...ever.
