Peer bullying has a long history, although over time, new forms of aggression have emerged. One of them is cyberbullying, which consists of using the new information and communication technologies, mainly Internet and cell phones, to harass and bully classmates (Del Río, Sádaba,, & Bringué, 2010; Garaigordobil, 2011; Garaigordobil & Oñederra, 2010). In recent years many studies have been published about bullying from a more traditional perspective, although there are few studies about bullying in social networks. One of the current forms of bullying (Flores, 2008) is to sending erotic publications (sexting) or erotic messages (texting) by mobile phones or the new technologies. There are more studies on the risk factors associated with social networks than on the risk factors associated with online bullying. Some studies indicate (Mascheroni, Ponte, Garmendia, Garitaonandia, & Murru, 2010) that among the risks are aggressive behavior and eroticism. In an investigation carried out at the University of the Basque Country (Garitaonandia & Garmendia, 2007), it was found that youths had access to violent and pornographic content, and that minors increasingly view such content and tolerate it with increasing indifference. It is relatively frequent for adolescents to visit pornographic webs, sometimes intentionally, sometimes casually through a click when seeking a word, and, although less frequently, some have had a date with someone they have only "met" online (Hasebrink, Livinsgtone Haddon, & Ólaffson, 2009). Other studies indicate the risk of addiction to social networks or cyber-addiction, which consists of the excessive use of cyber-technologies (Guan & Subrahmanyam, 2009). The possibility of a permanent, varied, fast, and anonymous connectivity to Internet worsens people's personal, social, and occupational problems (Weiss & Samenow, 2010). Another risk is the lack of privacy because of hanging confidential information on the web or leaving one's profile open to any cybernaut. The lack of knowledge about the loss of intimacy entailed by social networks causes adolescents and youths to use Internet without protective shields or without using adequate protective measures.

Taking the antecedents of the topic into account, the goals of the present investigation are: a) to describe sexting-bullying in social networks in adolescents and youths of both sexes, as well as victims' reactions; b) to analyze the correlations between sexting-bullying and the risk factors of eroticism, cyber-addiction, and loss of intimacy.
