Easy money - SkypeOut credit expiration scam

Well well well. This is one of the Terms of service that has passed under my radar. In the last couple of days, I noticed that my SkypeOut balance had dropped to 0.00. After a quick google, I discovered that it was happening to a number of people. Apart from the already galling fact that credit actually can expire from your account, the point that rankles the most is the lack of any warning message or email in advance. Would love to know how lucrative this little scam is for Skype/ebay...

In any case, I suspect this is not the last we'll hear of this.
