I think I forgot to vote about multiple aliases, so in case you continue compiling results, I would favor an outright ban, even for humor, etc. If someone was doing a "santa" type activity, they can simply set up a special email address for that purpose and ask people to send anything relating to that activity to that address.

Re: Drug testing... I am strongly in favor of that idea, although, I must say, I think some flyertalkers are definitely ahead of the rest of us who havent tested many drugs. I'm thinking any future PIP activity should be in a fairly liberal location if we are really to move forward with this suggestion.
