YouTube has just initiated a feature that allows users who leave comments on videos to delete those comments. Now when you put your foot in your mouth, you can take it back out.

"Whether you misspelled ‘pwned’, back in the day when you were just a n00b to the internets, or you simply said something you wish you could take back – now you can remove your commentary at any time," says a post from the YouTube Team.

Around two-thirds of children who say they have been bullied online have not received any previous form of harassment according to research from the University of California at Riverside published in the Journal of Adolescent Health.
