I'd say for a couple weeks just make 5-10 quick posts per day over there, no specific goal in mind besides sewing some testicles to those losers.
Then in a couple weeks when you've established some street cred there with solid posts and threads, we can have a big staged discussion with all points of view accounted for by us.
And just because you've been banned doesn't mean you can't still post. They are pretty slack over there and have twice the population and half the number of mods as we have here.
edit: I'm just waiting for the traitor amongst our crew to be a **** and make a link over there to this thread.

and, a better way of being covert is just to PM some of the more down-and-out members over there with a link to a relating thread on this site. Using PMs flies under the radar of the mods and can accomplish just as much, if not more. also, people are less inclined to involve their ego because nobody else is seeing what they write.
