I think the main problem is since they have gone to "Ebay" shipping instead of Paypal shipping. When you print a label on Ebay it takes the money from your PP account without you having to sign in to PP. It is called a third party authorization. I went into both of my ebay accounts and revoked 4 authorizations on each one, some of which I had no idea how they got there.
ETA - I just checked one of my accounts and they had put one of the authorizations back. I took it out again..
