Spammers are abusing Microsoft's online services at such an alarming rate that a non-profit spam fighting group now lists Microsoft as the world's 5th most spam-friendly ISP (Internet Service Provider).

The latest update of Spamhaus.org's list of the world's worst spam networks shows Microsoft at #5 because of 26 "current known spam issues" surrounding Nigerian (419) advance-free fraud e-mails (see screenshot below):

The comments from Spamhaus highlight the problems at Microsoft:

  • Months of LifeFileStore abuse, we see little done to stop it.
  • livefilestore.com - hacked by the tens of thousands.
  • spaces.live.com used and abused by spammers.
  • Pump and Dump spam anonymized via Hotmail.
