RE: Question on Blocking an ISP.

I highly doubt that 99% of email traffic you receive from aol.com is SPAM. Most likely, the email headers have been fudged to appear as if they originated from aol.com. ...and I don't think wholesale blocking of IPs is a prudent practice. First off, AOL, as I mentioned, is huge....why would you want to cut off your user base from communicating with the user base of the largest ISP in the world? Secondly, it is just against the spirit in which the internet was created. The idea, for better or for worse is to keep the networks connected together....if everyone started blocking everyone else...pretty soon we'd have islands of IP networks and the internet wouldn't be too internetworked.
