I would hope that in some cases, if their friends and loved ones start explicitly signaling their distrust of NewsMax or whatever, then their likelihood of seeing content from shitty sources would decrease, slowly extracting them from the hate bubble. Of course these systems could also cause people to isolate further, and get lost in these bubbles of negativity. These systems would help to identify people on the path to getting lost, opening the path for some IRL intervention, and should the person chose to leave the bubble, they should have an easier path towards recovery.

Either way, a lot of those networks depend heavily on inauthentic rage porn, which should have a hard time propagating in a network built on accountability.
