Just had a right good laugh at Elegant Turtles thread on WGs using Snapchat.
I'm not a social media fan myself but I do have Facebook. Those familiar with FB will know that you often get prompts about 'People you might know' usually because you share mutual friends. Well guess what, I got such a prompt one day and to my surprise one of the subjects was my regular.
I have never told her this and even knowing her real name I don't know her. But to take it one step further, following a trawl of her friends, her sister turns out to be a 'FB Friend' of a woman I work with and my niece, although I suspect this was thru an ex boyfriend as he is also listed and I've never heard my niece mention her. Luckily the trail ended there so nothing too close to home.
Not that I suspect she would ever want to turn me over, its good info to have in the back pocket if things turned sour!!
