But my point was: Is it considered accountsharing if a friend played your toon WHILE you are physically there and watching, and you never gave him your account information?
If I had to make a guess, I would say that Blizzard would almost certainly take action against your account(s) under this scenario. The way they see it, if you play another person's account under any circumstance, it's a violation of the rules. This avoids them having to judge whether or not you're telling them the truth about your friend's permission and cooperation (after all, how do they go about verifying this?). Blizzard takes account ownership extremely seriously, and so they take a very strict black-and-white approach to dealing with it.

Edit- Sorry ceph, for some reason I confused your question with the OP's. My above comment is directed at the OP.

However, in regards to letting a friend play the account for a short time, it's a ToS violation according to Blizzard. The likelyhood of you getting caught and actioned is very small so long as this occurs within a computer or computers that you typically use to access WoW (ie, they would assume that it's you playing your account, not someone else). I think it's an issue like what I described, that because of the way they consider account ownership they don't take any chances at all and are very strict in interpreting what is a violation.
