Why is this a scam accusation then? No one is trying to scam you. You need to sort this out with Stake support and TBH they don't really have to do anything for you because from their point of view you're submitting fake ID.
It is actually a scam if they dont at least let him withdraw his deposits. They let him deposit with this name.
ALSO, even eddie in the stream some weeks ago said at the level 1 verification you can easily type in whatever and still get the 10% more bonus, and if necessary change it at a later point. Those are facts.
