Only problem is how do you know who's MSN was hacked due to the DB dump or the MSN exploit, don't really see a way of knowing that unless Microsoft are willing to help out.
By the way its not only sythe msns getting hacked this is occurring on several websites including HF, BA, MMOE, PB, and probably more, I don't believe most websites are aware of the hackings, it appears to be an exploit that a few people figured out about and decided to use to scam some rsgp.
Weird how there's nothing in the News about Windows Live being hacked, pretty sure all the other major forums out there are going haywire at the moment.
