It's not me, but I'll caution that you're sailing a bit too close to a threat there James! In my opinion you're also overinvolved, albeit in a different way.
Basically it sounds like they've extended the same kind of non-punting contact to these guys as they do with you, and the other punters have read more into it than you do. That questions their (the WGs) judgement and behaviour too.
If they feel harassed or threatened they have the option of reporting it to the Police. It's your choice but I recommend that you don't get involved.
Edit - However angry they are, it's incredibly indiscreet for a prostitute to convey one punter's personal details to another. I'm referring to location, family, etc rather than the concerning behaviour.
