Most of Reddits alternatives from when they did crap in the past were typically flooded with extremists, racists, etc because the offshoot platforms had the goal of being an absolute free speech platform and only banning for illegal stuff. If there was a big enough influx of normal people then it would typically start to balance out. IIRC a lot of those alternatives had creators that were err…more politically motivated individuals but they typically stuck to their guns about having a completely open and free speech platform for better and for worse. I like the Federated approach to this because that basically means you can set your instance up however you want, and if the direction that instance goes is not the way others want well you can defederate from them and have your own little federation/blob of like minded instances and this goes the other way too as if you dont like what another instance is doing you can defederate from it yourself. At least thats what I understand
