Nobody gets booted unless they get Korihored. That didn't happen.
You started out by suggesting shatter2 may not have all sides to the story, and yet you posted "That didn't happen" as if you DO have all sides. There are only 3 ways you could know for sure "that didn't happen", as you claim. 1) You're a mod, 2) The person told you he was going to deactivate, or 3) a mod told you.
So, I'm curious: if you are certain he did not get korihored, how did you find out? I know you're not a mod, and I'm pretty sure said poster didn't tell you he was leaving. Unless I'm mistaken, that means a mod would have to have broken the rules and shared private information with you.
I think I'd be pretty bugged if that happened, and I'd hope the mod would be dealt with.
