"Forum spam
Spamming an internet forum is when a user posts something which is off-topic or doesnâ??t have anything to do with the current subject. Also, a post that doesnâ??t contribute to the thread whatsoever is also considered spam in some cases. A third form of Forum Spamming is where a person repeatedly posts about a certain subject in a manner that is unwanted by (and possibly annoying to) the general population of the forum. Lastly there is also the case where a person posts messages soley for the purpose of increasing his or her ranking on the forum."
