Regarding your post on 495: that thread has been locked for 2 years. If someone would like to make a new thread with updated information with credit to the original poster, that would be fine.
The thread you reported is fine where it is. It is not a game, but a thread about wordplay and the wordplay is related to Runescape.
Additionally, it was not gravebumped. The author actively maintains that thread. Even if it had been gravebumped, gravebumping is allowed under the current new temporary rules.
