However some criticism about using social media should be noted, for example not all society groups are presented equally in social media and their main consumers are young people. Also there are criticisms about trustworthiness [22] and reliability [23] of using data from social media which look quite reasonable. Despite these criticisms, we believe that the study of social networks is important and can reveal information about processes that are hidden or can’t be directly observed in society.
