To begin with, those pictures could exert negative influences on adolescents. Adolescence is a transitional and immature stage of physical and psychological development, a stage that could be readily and deeply affected by outside world. For example; many Facebook users, especially adolescents, displays references to alcohol and substance use on their Facebook profiles. One study of alcohol displays on underage college Facebook users found that 35 percent participant profiles displayed alcohol. This trend continues to increase dramatically. One of critics claimed that sometimes, those teenagers posted such pictures just to look cool, but in fact it led to imitation and even frenzy among friends. In addition, a piece of striking news made on the front page is that a girl from Taiwan posted her Porsche car, hundreds of luxury shoes, and even a private jet plane on her homepage. Then, after a week, thousands of photos about luxury brands, private boats, and decent villas appear on the Instagram. Form these examples we see photos shape false values for teenagers.
In addition, exposed phones might bring unintended consequence. By statistic, most of network profiles are set ‘‘ visible to public’’ meaning anyone can access the profiles that users have updated. Once those pictures and photos are targeted by harming users, these would put people at a higher risk of being stalked and then raped or even killed. The RANN ( the rape , Abuse and Incest National Network ) has released a report that there are millions stalking each year in America. Of course, one in four reported experiencing cyber stalking. What’ worse, due to safety holes，some sex offenders always find a way to access to picture of young children; stalk them by hints photos left and then committed crimes at last. Thus, it is parent’s responsibility that stops uploading life pictures about children’s for their protection.
Assuming above, although keeping records might leave an unforgettable memory, posting photos with geographic information would not only definitely make strangers aware of their location, and thus leads to uNPRedictable risks for users, but also mold false values among teenagers.
