I suppose you mean you get a 403 not a 503.
No, I really meant 503, because I was talking about the exceptional case where the host does step in and slam the door on a visitor. That only happens once or twice a year. The ones I lock out via my own htaccess get 403.
I guess lol is about all you can do when the alternative is to beat your head against the wall and scream in rage :)
I'd forgotten about it, but there is an ongoing thread about the Dark Side of Comcast over in the Search Engine Spiders forum.
