im no pro but ive made one before without a CC they could find your personal info if you dont use a proxy or a bad one which leaves you dns in the header.
If you've got no experience when it comes to Paypal leave it alone as it's way to risky. Proxies wont help much either, I guess you'd need to be a professional hacker bouncing from 20 diffrent servers around the world to make it work.
My advice would be to just leave Paypal alone. Personal information is easily retrieved even through you registered your paypal account with false it's traceable right back at you.
