XO / Concentric's abuse dept. is completely worthless. They are either
under staffed or just don't care, either way the net result is the same,
they're completely worthless. It's probably in your best interest to
just start dropping packets from those hosts. On my home network, I drop
their entire block because I have so much distaste for that ISP.
