I agree with Purist to not feed the trolls attention. They are obviously are looking for something they cannot get from their real life. It is best if people just ignored the garbage.
I did some home work and found Tony was slandered which is hard to not react. But the best long term effect would be to ignore these people. You can ban IP addresses all day and they will still come back in one form or another. We better focus our energy in being positive and nurturing those who have been affected by this negative attention.
