unfortunately the law does not cover what goes on inside a private online game between players. It does cover players causing damage to the game owner & vice versa -- which is why there is that ToS along with its copious amounts of liability disclaimer legalese. Realizer that Rohan is a private system that you are granted access to by PWI. Thus it is not a public facility freely acessible by anyone. You have to agree to PWI's ToS and agree to their liability disclaimers to play here.
Problem is that the onus would be on you to prove the value that you lost. You can't do that with virtual goods in a secure access game since virtual goods have no tangible value in a court.
The exception is if RPs were directly stolen from your account. Again it would be on you to prove how much and how they were taken.
We are all playing on an online gaming system. Penalties are limited to accounts that are in violation are closed. Nothing more. There is no compensation unless the powers that be -- PWi --- decide to provide it.
Any and all legal recourse would need to be raised between yourself and PWi since they are the ones ultimately responsible for everything that happens in their systems.
You can of course verify everything I have written here with your lawyer.
