It described Substack's content moderation policy as "lightweight," with rules against "harassment, threats, spam, pornography, and calls for violence moderation decisions are made by the founders." As of late 2020, large numbers of journalists and reporters were coming to the platform, driven in part by the long-term decline in traditional media (there were half as many newsroom jobs in 2019 as in 2004). In 2020, The New Republic said there was an absence of local news newsletters, especially in contrast to the large number of national-level political newsletters. The New York Times columnist Mike Isaac argued in 2019 that companies like Substack see newsletters as a more stable means to maintain readers through a more direct connection with writers.
