I was delivering an eSafety staff meeting last night and somebody asked me why you had to be 13 years and over to be on sites like Facebook. I told them that this was the age you are legally liable for the content you post on the web. They then asked for proof to show a parent. THe thing is that I don't know how I know this. I must have got the information from somewhere. I have googled it and get many sound answers why but not an actual official reason. Am I wrong? Anyone know where I can find the info please?
