You do not have the legal grounds to pursue me. Try if you want. You might think I am just another player, but I have enough financial assets and connections to hire just as good if not better lawyers than you. I have the legal grounds to pursue you but am choosing not to currently because the cost in legal fees and my time spent outweigh the eventual sum I will reclaim. You even admitted just now "the bug was your mistake".
