I am receiving loads of open relay scans from concentric.net / xo.com
netblocks. Contacted their abuse department five times last week but the
intensity of the scans only goes up when I do so, and I never get any reply.

Anyone has similar experiences with these people? Am I wasting energy?

Oh, the scanning IPS are*.

Anyone know what to do about these guys. What is the best way to stop them,
apart from blocking the IP range?
