When did Microsoft hire the Soprano family to manage Hotmail?
It's one thing to charge for email transit and storage, but it's quite another thing entirely to delete inboxes and sent mail folders after you (as a service provider) have overloaded them with SPAM to convince your potential customers to pay for "more storage".
Isn't email is one of those sacrosanct types of user data? Isn't it standard to bounce incoming email when a mailbox is over quota? Since when did it become acceptable policy to delete inboxes, sent mail folders and spam folders when a user goes over quota?
The most surprising thing of all is that the 110,000,000 users at Hotmail haven't started leaving in droves....
