I have thought about this for some time. What about an End User License Agreement? (EULA)



I know it is used for software, but surely it could be used for a name as well.



You know, Grant them temporary license for the purpose of making you money, but not for making them money. By using your name adversely, blah blah blah...



Whatcha think?





I haven't had time to break open one of the EULA's, but everyone accepts them.



Or, we could just not respond until they agree to the contract we send them.
