Facebook may allow under 13s

Facebook may soon allow kids under the age of 13 to join the site, as long as they have parent supervision...

I mean loads of people under 13 already join the site so...!

The main reason for not letting under 13s join is cyberbullying, content that isn't appropriate for children and contacting strangers...
Hang on!

Doesn't that happen 

already with people elder 

than 13??!!??!!
