Moderation is really hard, and the Mods want to make good judgment calls. A lot of what Natway does seems clearly wrong to us posters, because we're imbedded in those forums . Or I was until Natway chased a lot of folks out with above described behaviour.
But there are some things in forums that are really clear. Creating an additional account to support debate with yourself; that breaks ALL the rules of pretty much any forum. Easy to check via IPs, and black and white if so. If that was the case, I'd expect Natway not to be back.
Whatever the case tho, that's up to the Mods using their best judgment with the data they have. Their forum, their rules.
