AOL has the authority, but i suppose absolute power also corrupts absolutely! My clients have been blocked out form all AOL accounts --- and they DONOT spam! I pay USD 2000 p.a. per IP and AOL seems has blocked the IP --- not to mention the Domino efect it has , other ISPS like Road Runner and all also will be blocking the sites --- and I thik they already did!
I think it is high time we start differentiating between Spammers and small business owners.
