I'm in the opposite boat: I told paypal I was under 18 when I was under 18, called them, they kept my account locked, but as soon as I turned 18 I was unblocked and could used my original account. And I made the account when I was 11.
They figured out that I made my account a few months before my 18th birthday and permanently locked my account.
It seems all of this is arbitrary more or less random bullshit.
PayPal really kept a dormant account with an underaged persons PII for 7 years? Interesting.
Paypal was founded before there were any laws about age for signing up for things online, and minors are legally allowed bank accounts that their guardians don't have access to. (Or at least they used to be allowed: I had one at 14 in 2002).
