Wow, they sure layed on the BS pretty thick. This isn't new, though. I 
have a friend on Cox, and he was being scanned months ago. 
   I'd like to know why they're so freaking upset over servers--even 
ones going out--if you're not using  up a whole lot of bandwidth. If I 
wanted to set up my own pop&smtp mail server (mostly just to learn how) 
would they send me a nastygram? It's just email--that would be less 
traffic than browsing the web. Or even a web server. Would my piddly 
little homepage screw over everyone else on my switch? Not likely.
