Well, i did not fake my ID or fake stuff but:
Paypal is obviously saying in their policys you have to be 18
If you are not 18, they can lock, and limit your account, at any time, even if there is money on it.
However, i had the same issue, i did exactly the same, and i had like 50€ on that account.
So i just called PayPal, they were pretty nice, i just had to make a new account, confirm all informations again, Bank, Phone, ID and stuff
When i was done, i called them again, because they told me to, they just transfered the money to the new account, no problems here, it was a while ago, but i guess i had to wait a few days.
But in the end, new account, no money lost, no problem
Hope this helps
