ActivityPub relies on a lot of POST requests being relayed from instance to instance in a full mesh style of networking. I have a lot of doubts about its scale, and also it's reliability in federating important actions like moderators removing offensive content. I'm going to need to read through the spec to confirm if this issue has been addressed, but there really needs to be a way to send multiple activities with one POST request, guidelines for retrying activities to ensure eventual consistency, and to accommodate message queues.
