Giving the account information to your friend so they can level while you work or do arena for you would probably get your account rolled back, toon deleted or gear removed.
This.

Let's not guess what is and isn't within the "spirit of the game". Only Blizzard can say what that is. And I agree, it's sucky to have something so vague in the rules.

Another part of the reason why account sharing isn't allowed is because you're supposed to be able to have an equal opportunity compared to other players. Granted, RL will get in the way and some people won't have as much time to play than others, but if you allow account sharing -- even as minute as "letting a friend check it out" -- then you're opening the floodgates to shared accounts where people can play almost 24/7 and achieve more than the average user would be able to.

If you want to "let a friend check out the game" you can very easily get them a trial key without compromising your own account.
