Re: [44net] Portal registrations

I think I would try farming email addresses and license history via QRZ.COM and if they don't have a reference to an email or active callsign simply delete the assignment and DNS. An expired call implies a changed call or SK. Second level, assuming they passed the valid call test, would be a ping test to the allocated IP or a post card. But I'm not inclined to spend a lot of time or money on it.

Tedious, but it can be done.
