Why don't some of you softy wimps give them a key to the city, take them to an upmarket cafe and while enjoying a cappuccino and croissant just tell them they are naughty people. Put them on Newstart allowance and they can take a course on how to light a more responsible fire or at least light a fire with more compassion. That should solve the problem your way.
Now is the time to be ultra tough and use the sledgehammer to reduce the problem from many fronts. New building and planning codes strictly enforced and come down tough on the scum that must be laughing at some of these pussy posts.
