While Bebo is great in enabling people to stay in contact with friends and family members, parents need to be actively supervising their child's use of it.
Parents should first be aware that though one must be 13 to have a homepage, all that is required is a birthdate, meaning that children younger then 13 are easily able to sign up by simply lying about the year they were born in.
Parents should also be aware of things such as the Daily Babe application, in which the person who has added the application is sent a photograph of a young woman who they then rate according to looks. Most of the photographs are rather pornographic, meaning your 13 year old can now quite easily access porn daily.
Users are also able to put "stickers" on their homepage, which are pictures of often quite sexual and/or violent content. And Bebo is a prime location for cyber bullying.
It's a great social networking site, and can be heaps of fun for teenagers, it just needs a lot of parental guidance.
