Threadbombing
From TribalWar
"Replying to threads of his where the last post was two to three++ days ago.. just to bring all his threads to the front page.."
Categorized by the characteristic and deliberate replying to someone's threads in order to have them all appear on the front page, making it seem as though the person has been posting much more continuously (and thus annoyingly) than they really have. A form of forum sabotage.
[edit]
Etymology
The term threadbombing harkens to a similar internet word of recent invention known as Googlebombing. This was a strategy where webpage designers linked to certain pages in an effort to bring them to the front page and the top of search results - thus threadbombing is naturally related.
