There are online sites where you’re an avatar who makes social acquaintances with other avatars. While there are some women, you find many women are attracted to other women and some of the women are actually men pretending to be women so they can hang out with all the women attracted to other women since they are more plentiful than the women looking for men.
With most online dating services, you must start with the general premise that the person on the other end is a liar and work from there.
With the advancements in artificial intelligence, you can’t even assume are talking to a human being anymore.
