That is what I was thinking the other day, like, how would the account wide ignores work on the forums when the forums work differently to how the game does. Since the forums work where we’d need an account, it leaves us with either adding BattleTags to the forums, or another form of way to identify the account.
Now, truthfully, I don’t think we need to reinvent the wheel when there is nothing wrong with the original wheel, so BTags would have to be the answer.
