Ok so
First: you are right, you did not did that to you're name
Second: if you did not showed you're password like he said this would not happen (he may be lieing idk)
Third: he did not gave the account back
He did show his password and email he made it and then he deleted it and then that's how we got on his account so yeah he knew this was going to happen if he did this on his other account and now he's probably going to do it on his third account as well
