Legal or not?

Since I can never get Stefan to answer me anymore maybe he'll reply to this.
What exactly is and is not legal on a free server?
And why are you making every world p2p? I mean with that stupid ghost mode, isn't it kinda stupid to have to pay to play on a free server that can't use the p2p stuff?
Without the use of free server Graal is going to be reduced in player count big time, thousands of people will leave and play other games because their not gonna pay to have their account activated when all they want to do is play on a free server.

Remember, what I really want here is an EXACT list of what is and isn't legal on free servers.
