Good call to abandon your pursuit. This seems to happen more than I thought. Some amateur detective work can dig up all sorts. One girl I contacted had used her personal number on her profile. Doh. I found the car she was trying to sell as well as details about the petcare services she also offered. Oh and her real name. I didn't even look on social media.
What would you do?
I'd tell her. Both sides want anonymity and discretion. If she freaks, so be it. You've done the right thing (IMO). Furthermore, a reality slap for her might mean she's more discreet overall, which is good for punters (and you should you decide to meet her).
Should I post a link to her AW profile?
No. Some twat might use this as leverage over her.
Are we and/or the ladies we meet all in danger of being outed?
For sure but it's all about minimising the risk (unless you honestly don't give a fuck) so a dedicated number and email are a must for both punter and WG. I wouldn't dare see a WG who was known to be indiscreet.
