ok, I'll bite.

Does civilian ATC sometimes work a hot MOA? How/why/when ?

The closest thing to "working" a MOA ATC (civil or military - the US NAS is
a single system) does is turn it on or off and watch for spillouts.

This may be done by an air traffic controller if there is no MRU responsible
for the MOA (fairly common around USAF UPT bases).

Who "owns" any particular MOA at any given time and what can or cannot be
done in them depends on the LOA between the facility whose airspace the MOA
is in and the agency responsible for it.

Sometimes, it may be possible to coordinate passage of IFR aircraft through
a "hot" MOA, sometimes the MOA may go cold and sometimes the MOA
*can't/won't* go cold and IFR traffic has to go around. Depends on the
situation, location, and procedures.

In the old days of fighters with one UHF radio, aircraft in a MOA were on
the MRU MOA freq monitoring Guard. These days they've got way too many
radios and can be on multiple freqs simultaneously. Sometimes those
multiple freqs include ATC; sometimes they don't.
