thread delete when usergroup changes?

[nicklfire]

Hey there,

I am trying to figure out if there a mod for what i am trying to do.

Here is what i am trying to accomplish.

Basically i have a fish aquarium forum. I have a subforum called "breeder" and i have a subscription called breeder.

Basically ONLY breeder usergroup paid subscriptions are able to start threads in the "breeder" subforum.

Lets say that the member has a 30 day subscription to post threads in that forum, after the 30 days subscription if he does not renew his usergroup goes back to regular. Is there a way for the system to automatically delete or move his threads in the breeder forum once his usergroup changes back to regular registered.
