Facebook has a new safety page
It's about time Facebook took safety more seriously. They've recently put together a task force to help make Facebook more safe. So far they have put together this page with some information for users, parents, law enforcement, educators and teens on how to be safer on-line and not just on facebook.
Sure a lot of things seem like common sense, but there are sections within the specific categories that help to answer a lot of the FAQs I'm sure Facebook staff get all the time.
One thing is for sure: they recommend blocking and reporting quite a bit. I personally recommend making good use of the privacy features.
