He also speculates on the emergence of "anti-social media" used as "instruments of pure control."[176]
Courts do not always admit social media evidence, in part because screenshots can be faked or tampered with.[78] Judges are taking emojis into account to assess statements made on social media; in one Michigan case where a person alleged that another person had defamed them in an online comment, the judge disagreed, noting that there was an emoji after the comment which indicated that it was a joke.[79] In a 2014 case in Ontario against a police officer regarding alleged assault of a protester during the G20 summit, the court rejected the Crown's application to use a digital photo of the protest that was anonymously posted online, because there was no metadata proving when the photo was taken and it could have been digitally altered.[80]
