To the most recent poster above - You may or may not be correct in your assumptions. However, F Mods can only moderate based on what is posted on the forums, not what happened in game. As the post stands, it is not really breaking any of the Forum Rules.

F Mods can not take any action on suspected price manipulation as we have no access to other players' information and trade histories to verify the suspicions.
If you suspect serious manipulation is occurring, you may send your evidence, from the forums, in-game, or other sources to Jagex via the
