[quote]There's really no way for them to tell if you unplugged your Internet , the power went out , or some fat Italian guy came in and smashed your system with baseball bat.

You are right if it happens once or twice, but you gotta remember that the servers keep a log of everything you do. If your gameplay in the Raid becomes a trend, it will be noticed eventually and can be monitored by an actual person. So yeah they can tell if it is being done on purpose or not.
