I have a 13 year old son and I have only just allowed him use of Facebook. I didn't really want to as I know what Facebook can be like with graphic material and cyber bullying, but most of his friends are on it and using it. I have made sure that I have full access to his account and set up his security settings as far as it will let me. The problem I find is that Facebook make no attempts to stop this graphic and violent material on the site. Someone comments on a video that it should be removed or it is disgusting, then it gets spread around even more to peoples newsfeeds. Although I find that people have the ability to watch or not to watch, but seriously... who in thier right mind would want to view sick videos like that, especially a 13 year old? Surely there are other sites which can offer that stuff. If Facebook want to allow it on the site, then they should have tighter restrictions and options to change settings for anyone under 18. It is not just the responsibility of the parent to watch what their child is viewing, but also the responsibility of Facebook to stop this graphic material.
