Asking for sex in order to get a job or promotion is the purest form of sexual harassment, and can get the offender sued. It is humiliating and demeaning, and something that should not be tolerated by anybody. I personally do not want to ever work with someone that coerces models into having sex in order to get a job, and telling a model they must have sex with the producer in order to get paid AFTER the job has been done is most likely a criminal act in most jurisdictions.

If the report is credible and you merely state that "A model that interviewed with me said XYZ director wanted to have sex before consideration" that is not libel, slander, or any other actionable event, SO LONG AS IT IS TRUE THAT THE MODEL DID SAY THAT TO YOU.

If a model did tell you that, and you believe the model, I personally would like to have that producer's name publicly revealed. If it is true, then that is a person I would not want to do business with myself. However, if it is not true, then the model that told you in the first place has some explaining to do.
