In this case, those who were banned were told to contact a forum administrator (which would be Mark/Chogon). As far as I know, everyone that emailed him has been unbanned.
What makes this worse is that it wasn't an actual forum ban, because the moderators don't have the power to do that. Instead, Veralun took advantage of the "anti-spam" measures and used his ability as a group admin to remove people from the group; silencing them without actually banning them.
As for taking it to higher levels, there was an email sent to Mark and RAWA back in March of last year. It called for Veralun to be removed from the moderation team, and was signed by several well known community members from a variety of groups (including myself, chucker (from MystCommunity), amonre/ddfreyne (who at the time was a Cyan intern), vidkid7, Whilyam, and Marein (from the Dutch Myst Community)). They never replied.
It was only when things escalated (and Whilyam started the original "Ending the Nonsense") that RAWA actually seemed to take interest in the issue, and his interest can be summed up as "We'll discuss it behind the scenes *lock thread*". Nothing appears to have actually changed, which is what makes me so doubtful that anything will change this time.
Mod Note: I merged Whilyam's "Ending the Nonsense (part 2)" topic with Hoikas's "Who else" topic. Let's not fill our forums with topics about another forum.
