My friend was at one point, not too long ago, a real EVE Online nerd. I liked to play it alright myself, but he was so into it he would buy in-game money from a 3rd party site so he could afford the best stuff. Anyhow, he kinda got out of it, thought of playing again, and when he logged in, he found that, instead of banning him, or forcing him to sell items to pay back the illegal money, they simply reversed the contract, causing him to pay back the money from out of his game wallet. Money he didn’t have, of course, leaving him with a massive negative balance. This might not seem like such a big deal unless you know that any transaction in EVE requires fees, just like in real life. Meaning not only could he not buy anything, he couldn’t sell anything either, and no one could even send him money to help him pay it off. It was a total ball-busting move - the only way he could earn money is from running tons and tons of missions for the relatively paltry rewards.
So anyway, I thought that was a pretty hilarious way to deal with that situation. What are some of your favorite anti-piracy or anti-cheating methods in games?
