I'd venture to say that this is the result of the following phenomena:
Block all APNIC and RIPE assigned networks at the border and all of the sudden, hack attempts and CC fraud disappear.
It's fan-%^&#ing-tasticly simple to do and so very effective.
And if I block the ARIN assigned networks, most of the spam I receive disappears. It's very effective. In fact, I can limit myself to blocking all email from Hotmail, AOL and a few other large ISPs in the US, and that'll take care of most of the spam too...

Yet both tactics, somehow, seem like overkill.. **SJS (stating the obvious) -- North Shore Technologies, Cleveland, OH http://NorthShoreTechnologies.net sjsobol@NorthShoreTechnologies.net - 888.480.4NET - 216.619.2NET "Never attribute to malice events more properly attributed to corporate greed." --Me, March 28th, 2000

If you block all APNIC, RIPE *and* ARIN blocks, together with some legacy stuff, most network abuse problems stop entirely. I have found traffic sourced from 127.0.0.1 to be generally clean though. -- Alex Bligh VP Core Network, Concentric Network Corporation (formerly GX Networks, Xara Networks)
