There are many many predators on the internet seeking Children to groom. Not just girls either. I recently attended a lecture in keeping Children safe on the internet that was organised by my Son's School. It is truly horrifying how easy it is for predators to get into your children's lives through a computer.
Do not EVER allow a Child to have a computer in their bedroom. And if you see them type in stuff like POS check what they are doing. It is probably something they don't want you to see.
If they have a facebook account, check their privacy settings that no-one can see their pictures. Do NOT allow them to show their age. Have an account yourself and make sure you are amongst their friends list. Make certain thy NEVER add anyone unless they know who they are for sure. Ad in.. they have actually MET them, be it a School friend or someone they met on holiday for example.
Unfortunately facebook have refused to put a report button on their site, (they have to lose advertising space if they do, which means they lose money )but Bebo and MSN have one.
It is an eye in a square. If your Child feels they are in danger they should click on that and report, this would include cyber bullying or anything that is upsetting them and they are too afraid to confide in a Parent.
Keep one step ahead of your Children on the internet if you can. It makes sense to know as much about the dangers as you possibly can.
Interactive games are full of predators. That includes stuff like Club Penguin and Habbo. There is another called 2nd Life, they have set up a section aimed at teens and guess what? It's where many many predators get to chat to young kids by pretending they are one themselves.
Please read fully the information in those links, it could save your Child from abuse.
