Liftban names a function, with lambda list (&REST WORDS):
Lift the ban upon a user.
#liftban REASON USER yes
NOTE: In order to un-ban a user, you must key in the literal word yes as the third parameter, and supply the ban reason as the first. This is to avoid accidentally lifting a ban.
#liftban CHEAT silly-biscuits yes
