Gregory's ServerIt is.
Though, it obviously comes at a cost. We're seeing a bunch of 502's slow response times, and long waits between a post and it showing up on the fediverse.
I'm happy to become a patron - just did in fact - however, there needs to be a standard, obvious avenue for a user to contribute.
Going through the server-specific "About" link isn't clear enough, IMO; we should let admins stick a "keep the lights on" link between "About" and "Invite people" in the server-specific links.
