What facebook does to kids Brains

Facebook rots kids brains. Facebook was started 7 years ago to just college people but now its open to everyone even kids under 13. Facebook is addictive, I personally spend hours and hours on in on facebook. I agree Facebook rots kids brains, I think Facebook is ok to use but not at the age of 13 or even younger since parents are helping younger kids get Facebook. I think Facebook should be strictly for people 15 to 16 years old cause it comes more useful to us for school and stuff.
