Yeah but couldn't they just make it so you could only auction house stuff from closed battle.net characters? Like even as it is now you can do "single player" on battle.net using characters stored on their servers. And then you can do the normal single player that doesn't need a battle.net connection.
Just doesn't seem like a necessary thing to counteract cheating at all-- none of the big problems with d2 cheating have anything to do with single player.

No problem!
