The internet has changed, almost everybody can go online, and moderating a website is not the same thing it was in 2010. The most fastidious and expensive task of any social network is removing bots, trolls, hateful users, and maintaining trust with users, and improve security. You can't have free speech without fair moderation. So making sure a social media can make its users trust you, feel safe and have healthy users to user interaction, is the most important issue.
