I think we can trust the moderators, they've proven as much in the past. I still found it weirdly uncharacteristic of Shandyr to go for personal insults, which was the case this time IIRC.
Other than that you haven't missed that much, this place is rather calm these days. There haven't even been any blue dragons shooting fireballs lately, oddly enough it coincided with your departure.. ^^
What? Do you think we wanted to ban him or something? He left us no choice! I am just as sad as you are about this, believe me. I liked Shandyr quite a bit. He brought a lot of life to the forums. He was a valuable member of the community and I had hoped and prayed so much that he wouldn't do anything to ruin it. We all have to follow the rules... no matter who we are or how popular we may be. Not following the rules leads to being banned. If we are to be fair, we cannot play favorites with people. I will always miss Shandyr and be sad that he was banned, yet I will still remember him fondly. Believe me, there was no conspiracy and no monkey business on the part of the moderators in this decision. Inciting rebellion and harassment of other users are very serious matters.
Still, life moves on, and there are still many other people here, both long time members and newly joined members, who bring joy to the forums! It is often best not to dwell on the past, but to look forward to the future!
It was a bunch of things, really. It's a long story, and it took months of deliberation (and like @Tresset said, we really wanted to avoid this). The reality is, there were serious breaches of the Site Rules and we could not ignore them simply because Shandyr was otherwise popular.
For Shandyr's privacy, we've avoided discussing the details publicly, as that (1) comes off as gossipy, (2) would amount to attacking a former forumite when they are not present to defend themselves, and (3) the Site Rules actually prevent us from doing so.
The important thing is that the Site Rules are being enforced uniformly. Fortunately, Shandyr has been doing okay and continuing to thrive on other fora, and we're happy for him--we still view him as a friend, even though he's no longer on the forum.
Yeah, it's not really convenient for us. This policy dates back to before I was even a moderator, and I've been a moderator for more than 2 whole _years_ now. Keeping these things confidential is a longstanding policy, and we don't plan on breaking a years-long precedent of privacy for our forumites.
Certainly not on his wall, of all places. This place should be for remembering his role in the community; not gossiping about the circumstances of his departure.
