Why are there so many creeps on the internet?

I really don't understand this. Is this how guys think you should meet someone? My sister who is fairly attractive tends to get random dick pics from guy's she has never seen her entire life. Usually they are also sending their phone number and asking if she wants to hook up. Or what also tickles me is for instance on a Playboy models Facebook page you see guys asking them on a date or telling them to IM them. Like are you serious? Do people not go out anymore? Another instance when my sister would go out on dates the guy would text her from his car that he was outside. Like what the mother fuck?!?! Grow some damn balls and walk up to the door. My sister is not some carnival prize.
