Foul Facebook?

Jenny raised the question of: From a young adult standpoint, do you think that "Facebook is evil" or does it generally serve a beneficial purpose in society?

I personally am guilty for being of the many people who are "addicted" to Facebook, but it's more than an addiction, it's a legitimate tool of communication.  Because of me moving around a lot (my move next month will be 19), I have lost touch with a lot of friends, but since I have found Facebook, I have been able to reconnect with them.  I even recently found one of my friends who moved to Japan when we were in 5th grade.
Though some people take advantage of this social network, I think it is FAR from evil.  Yes, some bad things can happen on there, no matter what there is going to be bad things going on.  Overall, it's a helpful site.

As with Jenny, I have used Facebook for many of things, and not just keeping in touch with others.   I have used it to organize events, and even spread the word of school events to reach out in the community- and it has always worked.

As to dip into the side where Facebook could be considered "evil".  There have been instances where older men (way older,  I'm talking like 50's) have messaged me asking for sexual and just rather explicit things- which are clearly NOT okay and I'm pretty sure that in the Terms of Agreement, Facebook bans such contact.


Question:  Why do you think people take advantage of tools such as the internet and use them for things that they were intended to?  Such as trying to find sexual relations via Facebook.
