Facebook Prowlers

Hello Everyone!
I am back after a much needed rest from the online world.
The first post in months is going to be about the alarming privacy violations that have taken place on the one site we have all become addicted to, Facebook. I dont want to slander anyones hard work and fortune but there is something that needs to be dont by the site technicians. I have learned that all computers have what the call an IP address, which is a lot like a stamp of ownership. So why is it that you can see on a telephone who had called your house by the name and or number but such a sight is unable to detect the stamp at which has accessed your site? They can, they are just lazy and probably somewhat responsible for the actions that have occured to such people whom are on this site. i have had, on many occasions experienced someone going on and changing my password, looking in to what myself and my loved ones are doing in their personal lives then emailing me to tell me all of this from a fake email address all the while hiding their identity...The way i see it, if they all know what i am doing on a daily basis then they will be able to see this blog, and perhaps change it and maybe comment on it as well.. Facebook is supose to be somewhere where you can go an meet up with old friends and chat and see whats up, it is a polite way of being nosey:) and being aloud as well. So when the people in charge are sitting on the beach drinking their martinis they should be considering on a way to stop this all from happening to a lot of people on a daily basis, they are rich and financialy stable enough to come up with some sort of security precaution to take to keep its users safe. Until this day comes, i will no longer use my account.
