query only the do-not-call status of numbers they already had in their possession. Although the CRTC had rejected the Query/Response methodology, citing grounds of operational cost and complexity, a one-number-at-a-time Query/Response turned out to be so operationally simple and inexpensive that it is provided by the CRTC, free of charge, without restriction, to anyone who cares to use it. Other jurisdictions such as the USA provide similar Query/Response functions to checklists of small sets of numbers simultaneously, also free of charge. Jurisdictions such as Australia protect subscriber privacy, precisely as envisioned by the minority report, by keeping the list in the form of a secure database, and providing only a "List Washing Service". The CRTC's decision to expire registrations is regarded by citizens' rights groups as a technical shortcoming that adds unnecessary operational cost and complexity to the system, as well as limiting registrants' freedom to express their wishes. On 17 June 2008, the USA made registrations permanent until the number is disconnected or reassigned, citing "...benefits to the public and to consumer privacy interests...". Another possibility to prevent using the plain text list as a list of people to call is to provide honeypot numbers, unique to each telemarketer. If a telemarketer, or anyone he has given the list to, then calls one of the honeypot numbers, stiff penalties can be applied to the telemarketer. If the originating number of a violating call is either foreign or disguised, the CRTC could apply the penalties to the telco which delivered the call to the subscriber's line since that telco acted as an agent of the telemarketer by delivering the call.. There is no indication from the CRTC whether honeypots have been implemented as part of the DNCL.
