Many spammers use dictionary attacks which have more successful hits on a large ISP than a smaller ISP. They may send out millions of messages all of which have to be handled by the ISPs whether they are valid or not. Think about it, a million guesses at the part of the address before @ntlworld.com will result in more identified actual email addresses than a million on a small domain such as @chopsmcpsdomain.com
