[Note: The forum announcement is temporary; this thread is permanent. Thus, the thread.]
Anyone caught posting on an alternate, or "sock puppet" account (i.e. using two accounts at once), will be banned for doing so (both on their original and alternate accounts). This includes using a new account if your old account is banned.
First offense: Two-week ban for main account, permanent ban for all alternate accounts.
Second offense: Permanent ban of all user accounts. (This includes using a new account if your account is temporarily banned.)
P.S. - Yes, this includes Matt Collins.
