When the economy started to tank our ad revenues tanked and the model as it was could no longer be supported. So we changed it so that users won raffle tickets for prizes instead of winning prizes directly.
We did not message this to our users well and the BBB got over 250 complaints about the change we made. It was covered on local TV in charlotte, NC and lots of other bad stuff happened. They could never take legal action because they never paid but they still tried. They posted stuff all over the web about how we cheated and scammed them out of the prizes they won (which we did). I was just the technical co-founder and did not have a vote in financial decisions but since I owned the domain people thought I was the head guy and came after me. Good thing it was always free to play.
