Just to let y'all know, none of these discussions about Sona are new: The mods considered the same outcomes and options as being brought up here. The issue was complex, not simple. If anything, we dragged our feet when it came to the ban; we wanted to be fair to everyone, including him.
It also did not entirely depend upon the mods making top-down decisions. Sona had just as much a hand in what happened to him as anyone else did, and his choices and behavior helped result in the outcome that occurred.
(Just food for thought.)
