When you are on rev share and say this it means you tell them to take the money and stuff their ass with it.
This is why such a move is a drastic solution. Usually the program does not pay you anyways when you tell them good bye. Until they pay you, you are the hostage.
Forget about things like "officially forbidden". Nothing is official. They all can change the terms anytime and write there that they have right to sleep with your wife and daughter. Just get rid of the thinking that there is something official, that deals have value etc. That is just your false impression that will bring you to bad business decisions.

If you talk to God, you are praying; If God talks to you, you have schizophrenia.
