Wbm in the game Runescape stands for Wanna Be Mod which refers to a player who is acting as if he has the power to ban people. Players act this way because Jagex (the makers of the game) promote well behaved players as Moderators.
"Omg stop telling him which thread to post in you WBM"
"Omg another WBM invading my thread"
"Stop reporting every person you see you dumb WBM"

Stands for "Wit Beyond Measure" in the Harry Potter fandom.
"Wit beyond measure is man's greatest treasure" was revealed to be Rowena Ravenclaw's motto in HBP when it is shown to be engraved on her diadem. Luna Lovegood also quotes her in OotP.
The abbreviation is used by fans who identify themselves with the Ravenclaw house and value system. On MyLeaky, for example, it is the official motto of Ravenclaws who aim to earn the monthly "house cup" by participating around the site a great deal.
