I gradually learned not to make judgements of the ladies in dating sites by their appearance on their photos.
I have made contact with ladies who put pictures of them in very revealing underwear, with tattoos, one had pictures of her with handcuffs, others holding a drink, etc. Many of these girls turned out to be genuine, sweet and sensible.
Whereas... there were many girls with pictures of themselves holding flowers or with their pet or dressed in formal clothes, sitting at their desk at work, a picture with mama, etc. Many looked just like an oridnary pretty girl next door. Well so many of these girls turned out to be scammers, complete bitches, demanding or asking me how much money I had.
I ended up making the decision to first talk to them (if they wished) to find out who they really were rather than moving on from the girl with pictures of her holding a pair of handcuffs to the next girl with pictures of her looking like Pollyanna before sending a message introducing myself.
The ones that really worry me are the ones that are evidently poor and take pictures of themselves in front of a Porsche or a yatch or a mansion or holding a (likely fake) Gucci bag, etc. These pictures do tell a story.
