We talk about great ways to use your street team effectively, but one of the ways I see those efforts getting squandered is on message boards... If you're gonna do the old "hit the message board" trick, at least get folks posting from different IP addresses on different days, or you're going to invoke the wrath of bulletin board or weblog moderators. Remember that fake buzz is worthless and real buzz is priceless. You can't pay someone to fake buzz, and you certainly can't muster it yourself. When trolling boards, align yourself with folks who have been members for a while -- those testimonials will be valuable, and true.
