On a board with a fairly large population, starting that thread would end up like this:
Nigga, you is BANNED! UTSU and RRRRRRSH or whoever
followed by this thread.
Since bitching is inevitable either way, I think coming out and saying "so-and-so was banned for such-and-such" is much better than
"Hey, why was this guy banned?"
Mods: "..."
"Well?"
Mods: "..."
It at least closes the door on a good number of questions arising from any questionable banning.
Banning people on based on moderator whim of the time ("dead weight" = bullshit) as opposed to some major offense by the banned is detrimental, not to mention rather selective enforcement of the "rules"
Are you feeling left out again?
