Well the way I see it from what LL has in the TOS, no it is NOT a violation of it.
Billing info is:
Name
Address
Phone #
Credit card info
Paypal account info
Email address
etc.
Having on a profile if the person's been verified through billing information or not is NOT a TOS violation.
All of you who've posted, check law books and definitions before spouting off! LL is NOT divulging any personal information that's used for billing purpouses.
