Currently we aren't federated however we are looking into protocols such as ActivityPub. It's certainly interesting. It's possible we could federate our posts however one component of our platform is that communities can optionally gate access behind a membership fee. We are actively targeting content creators to get them to host their communities on our platform and some creators like having the option to have private communities. I'm not entirely sure how that model would fit with federation if we go the route of federating our posts, but it's something I'm certainly looking into.

Any problem happening on reddit could also happen on a "decentralized" platform. Whoever is paying for the servers gets to call the shots. All federated options should be automatically eliminated from contention if we're taking it seriously as a reddit replacement.
