  In recent years, several free-speech social media platforms (so-called
"alt-techs") have emerged, such as Parler, Gab, and Telegram. These platforms
market themselves as alternatives to mainstream social media and proclaim
"free-speech" due to the absence of content moderation, which has been
attracting a large base of partisan users, extremists, and supporters of
conspiracy theories. In this comment, we discuss some of the threats that
emerge from such social media platforms and call for more policy efforts
directed at understanding and countering the risks for society.
