Your link shows if the person is verified with PayPal. The BST Trust badge shows that as well as the status of the address that the user has submitted during the transaction.
"Address confirmation is useful because it provides a way for a someone to verify if a member is using a location that is known through PayPal."
Now, as well as the two items that you are shown when the BST Trust badge is displayed, we also record the First/Last name, email and the full address that is provided. This will be useful for the authorities should they need it in the event of a scam.
You cannot get that information through paypal without doing a transaction. There is a big difference between being PayPal Verified and Address Confirmed. Read the page and the links from that page on the first post in this thread.
