You should consider you made a mistake somewhere, and/or did too much activity all at once (especially if it was not 'aged'). Perhaps you used an IP that Paypal doesn't like (won't service that country) or that it already cookied or associates your PC with another account, etc. You could always consider buying an already prepared stealth account (like a business account) that already has the verifying documents. Some vendors deliver such accounts with a zipped folder of a Firefox portable browser on which the account was created, meaning Paypal already cookied the browser. So if you operate the account from that folder, Paypal doesn't sense any change or 'suspicious activity' to trigger a limitation. You still have to ensure your transaction activity is not too "unusual" even if the account set-up and documents were good.
