Stack bad pub, reduce corp hand size to zero, make free Keyhole runs with the bad pub.
Itinerant Protesters never really did work for me. Corps already have to play currents or have ways to clear them, due to Employee Strike. But getting 3-4 bad pub is incredibly strong. You can shred assets or make repeated runs at no expense. Mining Accident is a cool card and it's not too broken; the corp almost has to give you the bp early because losing 5 and not being able to play operation econ is very rough.
