If your Steam account is nine years old, it now [edit to add: should] auto verify.
Doesn’t do me any good, my account is just shy of six years old, and my MC debit card still doesn’t work. I’ll be 60 before it auto verifies unless my debit card magically starts working.
There must be some under 18s whose parents got them a steam account nine years ago who are now verified.
I think I may have been cleared because I sent them the precursor to a consumer protections complaint because they wouldn’t refund a glitchy game. The account is not that old.
