That’s an issue of the front-end not the backend. The backend is where an open protocol is needed to break the parasitism of the social media companies. Whether users deal with spam depends on the moderation policies applied by this or that specific front-end.

Think of it as a filter. Reddit is a filter on a walled-in social network. What you post there isn’t visible on any other social network and vice versa. But because of that lock-in you are limited to whatever crappy moderation one specific front-end sticks you with, with no alternative if you still want to interact with that social network.
