Sec.  64.1512   Involuntary blocking of pay-per-call services.

   Nothing in this subpart shall preclude a common carrier or information
   provider  from  blocking  or  ordering  the blocking of its interstate
   pay-per-call  programs  from  numbers assigned to subscribers who have
   incurred, but not paid, legitimate pay-per-call charges, except that a
   subscriber who has filed a complaint regarding a particular pay-per-call
   program pursuant to procedures established by the Federal Trade Commission
   under title III of the TDDRA shall not be involuntarily blocked from access
   to that program while such a complaint is pending. This restriction is not
   intended to preclude involuntary blocking when a carrier or IP has decided
   in one instance to sustain charges against a subscriber but that subscriber
   files additional separate complaints.
