I mean, if people want to give out helpful information about gland enlargement alongside links to where supplements can be purchased for the astonishingly low price of $12 a pill, who are we to try to stop them? Provide an unfiltered free speech platform and the stronger ideas will win, right?

Just provide more effective tools allowing users to tune their own feeds.

With a profit or ideological motive, I can spam you, and shout over all meaningful communication much faster than you can block me.

Yeah, and the idea of a spam filter won.

Spam filters can be opt-in. Spam filters can be federated. Spam filters can be local. It simply isn't true that decentralized censorship resistant systems fundamentally require users to be inundated with spam.

I wish that were the case.
