When you submit a post to a thread and nobody responds, sign up with a couple of extra accounts. Make each of those accounts bump your post to make it more popular. This happens a lot on Digg, 4Chan, and so on.
This post really sucks, but 30 people bumped it. The same fag must samefag it over and over.
A person who posts trying to:
-act like more than one person
-bump a thread
This could happen in the following:
1. That person keeps samefagging on AIM.
2. Look at that samefag agreeing to his own post!
