Also allows people who are really probably not on the up and up (having something to hide) giving them the anaminity to do so. Don't you think? For instance a married man, who wants to come on here witout the possibility of being recognized. Scammers like you mentioned. They make up some fake persona, and live behind it. It is quite crazy what you can hide behind a monitor.
I agree you need to get to know someone in real life. Too many people hide behind the computer and forget how to have a 1 on 1 personal interaction.
