FYI, a "cease and desist" carries the same legal weight as me sending a one-liner saying "Knock it off".
They are strongly worded requests from a legal point of view. The only real message they send is that the sender is serious enough about the issue to have involved a lawyer, unless of course you write it yourself, which is something that literally anyone can do.
If you want to actually force an action, you need a court order of some type.
NB for the actual lawyers: I'm oversimplifying, since they can be used in court to prove that you tried to get the other party to stop, and tried to resolve the issue outside of court.
