Adding fares just means the nuisance riders will jump the fares. It won't stop them from riding.

If that were the case, the theory is that the issues would not have increased after they went fare free. The increase may have been due to something else, though. Experimentation is probably the only way we will truly find out.

Nuisance riders often have nothing better to do with their time and little money. They will find someplace else to go.
