At the end of the day very little that can be done to prevent kids from encountering online advertising. The best approach is to teach them, from an early age, the purpose of advergames, branded characters and commercial websites.
In this section, we examine some concerns related to online marketing.
There is little doubt that marketers love kids. With a collective spending power of over three billion dollars, and the potential to influence billions more in family spending,  marketers are keen to establish brand recognition and brand loyalty with children at increasingly younger ages.
Typically, youth sexting occurs in three contexts: in lieu of sexual activity for younger adolescents who are not yet physically sexually active; to show interest in someone a teen would like to date; and, for sexually active youth, as proof of trust and intimacy.
There is little evidence that sending sexts is by itself a risky act: for example, one study done with American university students found that many reported positive experiences. 
Studies about the gendered aspects of sexting consistently show that while little criticism is attached to boys who send sexts, girls who do so are perceived as being sexually immoral: girls who sext are seen as using their sexuality to get public attention, while boys – even if their sexts become public – are assumed to be doing it only to get the attention of one prospective partner. 
Parents, schools and law enforcement agencies are grappling with how best to respond to this issue. In the United States, sexting amongst youth has resulted in teens facing child pornography charges.
