[ale] blocked domains

Not always true that they block coputers.  They let you use it for a few
weeks and then cut you off.  

More interesting to me is why they would block a outside hosting domain?
I have not had problems with Bellsouth, but I could not get speakeasy or
speedfactory DSL.  I really don't see how blocking ports help.  And I
say this because they block the ports at the border not on the internal
network from what I can tell.  And this seems to be same for comcast.
So you can spam/scan or be spammed/scanned for your fellow subscribers
on the same WAN subnet.
