Thanks for clarifying that; I agree WP:BAN#Dealings with banned users says what you said (and that it's not in an obvious place; perhaps "Proxying" should have its own heading.)  And I'm sorry that I questioned your judgment.  Now, where would you draw the line between being "tipped off," or pointed somewhere as Bmedley apparently was, and posting on another's behalf?  Also, is this policy worded in an appropriate way  if a banned user asks to have something included, does that really mean that all of the sudden everyone is forbidden from including it?  If that were the case, a banned user could effectively censor just by asking to have the material he or she wishes to censor included.  I'm sure that can not be the intent of the policy. ←BenB4
