I never thought to ask that question before, as I never report/revoke.
Report/revoke passess additional parameters to spamassassin. According to the documentation
https://cwiki.apache.org/confluence/dis ... ortingSpam
, this will "... directly report your spam to the three HashSharingSystem it supports: see UsingRazor, UsingPyzor, and UsingDcc for details on them. "
I didnt find the definition of the revoke, but I'd assume it does just the opposite.
