how we can balance freedom and sercurity

I think that Myspace is more dangerous because more people have a Myspace then a Face book. Also on Myspace you put out alot of information like what school you go too, what your first and last name is, what you like, were you live, what your number is and your screen name, your email adress and a whole bunch of other things that people should not know because it is personal. Face book is more for kids like teenagers and younger kids were Myspace is for older people that know what they are doing and know what not and what information to put out to the public. The reason that Myspace is blocked and face book is not is because there are more predators and strange people that are capable of doing strange things that are scary and can harm you and possibly kill you.
