You wrote, "For email use AOL. Gmail and Yahoo are fine too."
But it sounds as if you're saying AOL is ideal. Why?
Also, with gmail anyway, when you create an account it makes you also provide a phone number for gmail to text you a code. This would compromise your anonymity, on the gmail end, just as the debit card knowing your SS# could compromise your anonymity. Paypal doesn't see it...but what if Paypal demands it from nFinanse? Or what if Paypal demands gmail to provide the phone # you gave for the gmail account?
Sorry if all the above questions are stupid. I'm sure at least one of them is.
