I had a very interesting message exchange with a young lady on a swingers website.
the chat then progressed to whats app and she eventually revealed her supposed real age ( below 16 ) I immediately told her that's it end of discussion and we never spoke again
Looking through my phone ever the weekend I came across a womans name in my contacts that I didn't recognise so I googled it, it's been reported over 100 times for attempted blackmail
So a lesson learned google every number i'm ever given before saying a word
