I had a client a couple weeks ago that decided to try sending out spam from our servers. Of course our TOS says we have zero tolerance for spam, and if you do there is no refund after 14 days. He was on our server for 18 days when I saw alot of mail coming out on the 14th day.. I watched the account and saw he was spamming. Long story short I canceled his account and he wanted a refund, I told him about the TOS and he contacted paypal. Paypal saw that was I in my rights and told him no.
