*nods* with Gizmo's idea. I would say set up a TOS and make it clear that "sharing" your info compromises the security of the forum and will be dealt with by terminating the primary account regardless of status. This will not end the practice, however, it will at least curb it a bit for you. You will have to be active in policing this, at least until people get the idea you are serious.
