If we just left it at that, I’d agree. Reddit had a handful of right-wing media watch subs that would track and report when someone said someting egregious, legally gray or in light with the fascist movement identity (e.g. mythical history to justify legitimacy.) That can not only be used to expose their mask-off faces to the public, but in instances where incitement or threats turn into action, it can be reported to investigators to help track down key players.
So, much the way backpage was helping law enforcement track human traffickers (who did business on backpage) we have the option of leaving them be, but to exploit their intra-sect candor.
This raises one of the problems with company-sponsored media that has been a problem since Pulitzer and Hearst. Your bosses and sponsors will always have opinions about what news is fit to print.
So during the cold war never a bad thing was said about GE (we bring good things to life!) despite how they were pushing our elected officials to buy more nuclear warheads, even when we had plenty. GE bought a lot of commercial time from all three networks and no one wanted to disrupt that cash flow.
This might be a benefit from federated social media, that burying a story becomes impossible requiring only a bit of vigilance from its end users.
