It was more than a little sad to find out that Electronic Arts was locking users out of their Origin games for getting banned on the forums. Thankfully, the account suspension policy has since been tweaked such that those with a ban can still play games they own offline:
"If you find yourself with a disabled account, please note that you can still play EA games in single-player mode. For PC games you will need to enable Origin's offline mode to play games with a disabled account. Go to the settings tab in Origin (the gear icon) and select Go Offline. If your account has been disabled, please follow the instructions in this article if you wish to appeal the action."
Well, that's something. Perhaps if the average person had the time and energy to thoroughly read the terms of service, there wouldn't be quite so many Origin users. Then again, the same could probably be said of most software.
