The infographic below relates to US data but I would think UK figures are about the same. Sophie is only 10 and already, most of her friends have got a facebook account and several of them have been victims of bullying or nasty comments.
This information was released by MinorMonitor, which is a free tool that enables parents to monitor their child's activities on Facebook, already used by several thousand parents. I'll definitely have a look at what it has to offer before allowing Sophie to create a facebook account, especially as it's free.
