Don't even need to play Devil's Advocate here.

I guarantee 100% that this is the exact reason. If they're truly deleting ALL your data, could you imagine the customer service nightmare if someone's account got hacked and the attacker could issue a request to delete the entire account with no method for recovery?

What's the point? Anyone can buy fake id scans for $50 at most, $20 if you aren't getting ripped off.

Blizzard obviously doesn't authenticate these IDs as that isn't really possible.

The fact that you can do essentially anything to a Battle.net account with just an ID scan is a huge vulnerability.
