It's an interesting one. I tend to give the profiles a go every so often. Sometimes it's just someone who's keeping themselves hidden from the neighbors, especially if they are doing incalls to there actual house. I've met a couple of tasty divorcées from blank profiles, and the story normally goes that so-and-so at number whatever was doing it so they thought they'd give it a try.
One of them was only on for a week, before quitting, I saw her and her bedroom had a stack of 'fifty shades of grey' type books. Obviously had a different idea in her head to the reality. Another one, had only seen one guy before me and he just sat and cried apparently, she was mature but with huge breasts and was really nervous (ah, don't worry love, you just deepthroat me until you gag and then we'll have a nice cup of tea).
Although, most times there is either no response, a weird request for specific details of what you want (which I assume is a guy getting his kicks) or a refusal to provide a picture (whatsapp can show you both your picture in relative anonymity).
Personally, I think the fakes and let downs are well worth it for winkling out those rare girls/women who are just giving it a go before vanishing.
