If he's resorted to harassing posters via PM, that definitely is grounds for banning.
Nope. Unless he makes a sock account, the moderators here don't give a shit.
Whereas mods on AAD don't give a $hit, period. Or I forget: Are we wantonly banning too many people, or cravenly not banning enough? It's tough remembering which you are arguing on any given day.
And ftr, be a tad more judicious (i.e. accurate) in use of the all-encompassing terms "mods".
(Which reminds me, I have a banning petition to sign in another thread.....)
The point of AAD is that it is supposed to be lassiez-faire outside of significant personal attacks. That being said, they'd ban CCSF right away if he tried to sign up there.
