Children are always one step further in the role of internet and social network users than we adults. At the same time, they often claim that they have sufficient information about online dating and security. But what is the reality? What risks do children perceive and what experiences do we have on the Safety Line? E.g. a common reaction is "I wouldn't just write to a stranger", but communication within online games, applications perceive safe "I write with a friend - a child who plays the same game". But is he really the one they imagine? They would also "never send their photos to a stranger." But they share and store their photos on social networks, no matter who can see them.
