Auto group depending on which forum you use the most

[Spank]

Hi gais! I'd love a mod which would automatically assign a member to a group depending on what forums thy have the most posts in. eg.

Member A posts mostly in the Spam forum he'd be put into the spammer usergroup, if he then post more in the say the movie forum he'd be transferred to that group automatically.

Would even be possible?
