I have reviewed draft-baeuerle-netnews-cancel-lock on behalf of the Operations Directorate, for the IESG telechat review.

Modula the issues raised in the Genart Review (abnf validation) and security ( pre-image attack protection) I think this is a largely ready to go.

Under the best circumstances methods for article cancelation aren't necessarily honored, are intended to  be employed by  a diverse group of end users injecting netnews agents, or moderators, asserting various roles in managing message removal and offer somewhere between poor to no assurance of efficacy. 

To the extent that this methodology offers an improvement  to the set of parties that chose to both employ it and honor it; it offers protection against spurious removal requests from within the scope of their systems. the protections offered by the MUST NOT in section 3.2 are weak as the message has no integrity protection of substance and any such assurance that demand is honored is a coordination problem between like-minded operators.
