And if I disagree with you in a thread, PM me 100 times in 45 minutes reminding me that I'm not God, and telling me that I'm a crappy mod, and letting me know that the one person who defended you is the only person on the forum who is a sensible and independent thinker. Then threaten to report me to the admin. After I tell you to go ahead and do it, but I warn you that the admin doesn't like to be bothered with juvenile BS, email the admin 50 times, and attack him too. Don't forget to remind me and the admin that you were once the mod on a forum too, which validates your opinion that we're both pieces of bleepin' bleepity bleep bleep. After you're banned, create another account and spam the forum by bumping a thousand old poll threads.
Another good tactic is to give repeated in-thread explanations of why I can't ban you. It's good to bring up unapplicable free speech misconceptions and jabber away about the sanctity of opinions while you're at it.
