A forum or image board trolling technique tricking users into posting on a thread with claim that they will win a prize or other reward for being the 'last poster' on the thread.

This, however, is impossible for most forums, as there is typically no limit to the amount of replies a thread receives, unless a site moderator or administrator 'locks' the thread so users are no longer able to post. This often results in the punishment of the original poster of the thread by the moderators and possible lulz.
