I suppose I should be pissed, but actually I’m quite excited to have stumbled across some serial numbers posted for one of my apps at http://www.coreserials.com/serials/pc/52799/spamevader-1.0.0.html It was a web-based spam filter called Spamevader which I no longer distribute. Never sold one copy =) It’s kinda of a weird validation. Having my app cracked makes me feel like i made it. ;-)
