Thank-you, will clean-up once out of beta, waiting on this to go live.

I do have a question, why are these ghost user generated?

Prior to you releasing this, this is what I was going to use and it did not generate any ghost user...

User would register as normal.

I then point the user to an external page via the registration redirect mod. which basically told them to verify there email for the activation email.

When they clicked on the email to verify there account, I pointed them to another external page which was redirected by the same mod I mentioned above.

This page basically offered them the possibility to continue for a free account, or upgrade.
If they selected upgrade, I them pointed them to the payment.php since at this point they were already registered.

I didn't test this intensively, but it seemed to work without any ghost users created, even if I stopped the paypal process.
