Posting unpublished WG numbers via PM is likely to get you barred from using PMs. An SP takes her ad or number down for a reason, including to avoid stalking, harassment and threats to safety. Whether a punter is new to UKP or has spent years here you do not know what he is like in person with SPs, especially ones he is trying to obtain unpublished contact details for. If you can't respect another person's privacy, especially in a dangerous environment, then perhaps losing your PM privileges isn't the only measure that should be taken against you by management.
If an SP has actually told you to pass on her information then that makes you a tout, whether you receive privileges or discounts or not, and management may well take a dim view of that too.
