On dating sites there is a common belief that if the girl is really hot and acting really into you, it is really a 40 year old, overweight man. Well in some ways this is probably true on some of the sites. Also you could be looking at a profile run by a computer or someone paid to attract people into buying a membership because there are women showing interest in you.
I have looked into several dating sites and very few of the adult 'dating' sites are legit. First they advertise completely free membership and don't tell you that the free membership basicly lets you set up a profile and does nothing esle. If you just keep a free membership you usually can't respond to any of the messages that you recieve. Now on most of these sites, I ended up getting flooded by messages from very attractive women. On the two sites I tried out memberships on, the messages from those women stopped as soon as I upgraded. So I have decided that there are two types of fake profiles, people paid to lure people in, and cyber bots(for the same purpose.) There are a few sites that had a common occurance of this, but changed the rules of the free membership to being able to respond to messages but otherwise not able to send them. Yeah, I ended up with no messages at all.
