Fake Buzz

Spin Me has some wise words on Message Board abuse.

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.
