Sorry, English is not my mother language
Jack, hidden behind your explainations, the real fact is you want to get more money increasing the prices. It would be easy to check openspaces or Class 5 lands with your performance testers and adjust fees or taxes for those who don't respect initial rules.
For my own, I refuse to pay more. I bought a full class 5 sim and I pay a monthly tier. Added to my premium accound, these are hundreds US $ I pay each year, not included my SL purchases.
So, if you apply these new rates, I'll downgrade my account and I'll leave my land.
I accept to pay for the service I signed for, even the whole system is freezing each week end. I refuse to be racketted.
