As the social networks become more and more popular, teenagers and kids which as young as six use those kind of websites more and more often without awareness of the danger which comes too. Their pages are browsed by their friends, classmates and strangers who also include predatory pedophiles. Ellie and Olivia¡¯s experience is the typical example and fortunately they are lucky than those victims. Putting your personal details like address, school and hobits are just like standing on the streets to deliver your diaries, photographs which can be read by anybodies. More shockingly, only 10 per cent of parents thought their children chat with people they don¡¯t know and only 13 per cent of parents know what their children have done on the Internet. To avoid the tragedies happens on teenagers, there are some ways. First, do not put the personal details on the internet and second, when somebody have some sexual request on the MSN, just say no. The last thing is that never let children get on internet in their own bedroom because these kind of children can easily attract those ¡®predatory pedophiles¡¯.
