Introduction Growing access to internet resources has brought not only the advantages of getting the necessary information or services. Along with receiving benefits, people may fall victim to serious dangers presented by hackers, trolls, phreakers, and other deviant and antisocial groups. Internet trolling is one of the most frequently used jargon words of our century. This activity involves causing harm to internet users with the aim of bringing enjoyment for the person doing this harm (an internet troll) or entertaining the audience this person wants to impress (Bishop 2013). The problem of internet trolling is getting bigger every day as trolls acquire more possibilities to spread their unkind word through the world wide web. The vast extent of internet trolling is partially explained by the diversity of the topics in which trolls are engaged. These may include political, sexual, racial, gender, and many other spheres where trolls exercise their provocative activity. Trolling fluctuates between dubiously distasteful and almost illegal. Trolls provoke their victims with illusively sexist or racist words, they post outrageous images with the aim of wrecking the discussion and fill the conversation threads with preposterous misinterpretations of other users’ opinions (Phillips 2015). The scope of trolling is unbelievably large as the trolls are apt to penetrate any subject one can possibly imagine. The trolls do not have any personal feelings towards what they are writing. Thus, they can write about anything. What gives them more freedom is that they are legally protected by the postulates of freedom of speech proclaimed in the First Amendment (Phillips 2015). Thus, the extent of trolling activity is rather wide, and it is getting bigger every day. Perpetrators and Victims of Internet Trolling Depending on what kind of activity brings the most fun, trolls are divided into a number of categories. There are trolls who love getting people enraged (“rabid flamers”), who luxuriate in correcting others’ mistakes (“priggish grammar trolls”), “crybabies” who threaten never to come back when someone hurts their feelings but always return the “never-give-up, never-surrender” type who always has to be right, and the “retroactive stalkers” who will not calm down until they have found something embarrassing in your history which they can bring up every time you post a thing. There are also such types as “lame teenager,” “self-feeding troll,” “bored hater” and “Nellie McNeggerson” who enjoy complaining and contradicting others (Grande 2010). “Sharing troll” is the one who discloses your personal information if he/she is angry with you, “profane screamer” asserts his/her opinion by writing in capitals, “white knight” defends someone even if nobody asks him/her for that, “expert” behaves as if he/she knows everything about everything. Other popular varieties of trolls are “spoiler” who reveals the film endings and sports match results, “fraud” who steals money or personal secrets, and “flooder” who posts the same thing repeatedly. Finally, there are “liar” and “stalker” types who both try to seduce others. The difference is that the “stalker” can actually be harmful while the “liar” is usually inoffensive (Grande 2010). Psychological premises for trolling are concerned with invisibility, anonymity, and the absence of real-time communication (Stein 2016). Trolls emphasize that unlike clearly abusive messages posed by flamers, their messages are merely provocative and meant to bring fun (Bishop 2014). However, revealing people’s personal data or causing conflicts is not considered funny by other internet users. The popular victims of trolling activists are the women defending the
