Time to read up on exactly how Mastodon works. I can see there being a need for payment of server hosting given the scale of new users at the moment. I wonder if you can self host your own “bits” etc
@mattwilcox Docs on how to run your own: https://docs.joinmastodon.org/admin/prerequisites/
Also there are various hosting companies that do the technical work for you. https://masto.host/ has been around for a while also maybe @Stuxhost has the same offerings (created by @stux mstdn.social admin).
