I use my old smart phone for punting but have few apps on it, certainly no social media apps, just Google maps and a few games to pass the time if I'm early. I know people are paranoid about being discovered, throw away phones, police letters, Linkedin panic etc but FFS, you'll get rumbled for knocking on a prossie's door or, "hey I saw you driving down X last week, what were you doing in that end of town?" in front of your Mrs, not because a a woman appears on FB as somebody you might know, I get hundreds of them every day, and even if they are a prossie it won't say, "do you want to be friends with that brass you shagged last week?"
I honestly think some people love all the subterfuge and cloak and dagger stuff because it increases the jeopardy, there's something about visiting a WG that goes above and beyond just a shag ,it's not just cheating on your Mrs, half the stuff that gets repeated on here about the stigma of being a punter is generated by the punters themselves to massage their own egos as in the civvy world they're just another bloke in the street, this is the only time they cross a line, except when the took a drag of that blokes "herbal' cigarette at the back of a pub in the 90s, that they retell every time they have more than two pints that golden 30 minutes between lucidity and throwing up.
