what would you think of awarding points to those who spend much time catching reposts, copyrighted pics etc. to help "the machine" find them?

Rob, I'm not sure about this as it would seem like a pain to police.  Also, the work to implement it would be rather substantial as the 'report photo' thing does not audit who makes reports and would require an entire system just for that purpose.  I'll keep it on the list, but have to say this one is a backburner type one for me...
