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.
