If you do this, you may as well start making bots for all of us to bot on Runescape with.
Making private servers (by law) violates Runescape's copyright.
Why?
You copied quite literally, their whole game world and you've only changed EXP/Drop rates.
Now, of course, for a game like EVE online, making a private server literally is not possible since they have hundreds of servers holding all the sectors, etc, together. But, I digress.
The point is, making private servers is against the law, dude, and you can get lawsuited.
