Thanks for bringing this to the list Fred.

We could put this on the agenda for the PING call on Thursday (18 October). Would you be available to introduce the specification and the issues you have identified?

BTW. Would you also send a pointer to the specification.

Best regards,
Christine and Tara

For example if a user decides a particular third party is not trustworthy and adjusts the CSP policy to block the third party then when an attempt is made to load the blocked third party resource the UA would be required to report the violation to the first party.   This is turn could be used to discriminate against the user.
