As I recall, certain Yahoo servers were blocklisted for failing to 
confirm subscriptions prior to spamming the hell out of people. I 
know I was "subscribed" to at least three porno-spam mailing lists 
hosted on Yahoo.

( is DNSbl listed. by blackholes.five-ten-sg.com

added 2001-11-06; spam support - refusal to delete yahoo stores spammers
