I "minimize annoyance" by simply blocking chronic offenders outright.
(Strictly, this doesn't quite minimize annoyance; I accept slightly
increased annoyance potential in the hope of actually fixing the
problem.  But anyone who continues after three or four complaints to
the site's postmaster, or which challenges postmaster mail, gets
blocked entirely.)

Exactly.  I'm willing to deal with a little annoyance in the hope of
getting the actual problem - the futile abusive behaviour - stopped.

But not more than a little.  It doesn't take too many challenges
without action before the blocks go up.
