Appropriate punishment...
I think that an appropriate punishment would be that the same information that was posted to Craig's list for the 17 year old be posted about the 40 year old woman. She should not be allowed to change her phone number or employer for 4 years, must answer every call made by respondents, and listen to them for at least 5 minutes each call. Failure to do this would result in reinstatement of the original prison sentence (assuming she is found guilty). Call it alternative sentencing...the prisons are too crowded right now. She should be all for it since she thought it would be a good joke.
