I guess I was just sort of surprised that this was a post. This happens to every single person/company who sells products, whether on the web or in person. You will always have a cat and mouse game between "potential customers" and your business model. I can't remember the various stories through the years but it reminds me of when a guy bought loads of Jello to earn free flights (I think that's what it was?) because he calculated that it was a great opportunity. It "wasn't in the spirit of the promotion" but it wasn't against the rules. The promo was, of course, canceled. The point is that you have to have a TOS that gives you a certain latitude to deal with things like this at your discretion - something similar to "We reserve to cancel any account at any time for any reason". KI would also suggest you start putting in IP address controls/ability/logic. Something like "If there are two accounts from this same IP address within the past 30 days that have both accessed the freemium subscription yet have not converted to premium, do not allow a new freemium signup from that IP within x days." - or whatever. Just throwing out ideas. Surprised this is the first time this has happened to you.
