Custom feeds are the solution.
Or maybe a new algorithm for local "algorithmic" feeds is to sample notes from accounts so one of them doesn't dominate the feed. nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s
Or perhaps just a different UI approach that gives each account you follow a limited static space in the feed so if it spams you will only see the last note anyway -- this could be like treating each person you follow as a standalone Telegram channel in a Telegram-like UI, for example, or doing something like https://fraidyc.at nostr:nevent1qqs8s9ve4gak44drxknhldx953tf6fgkkg3r5m06arrls87d79aj6kgzyqalp33lewf5vdq847t6te0wvnags0gs0mu72kz8938tn24wlfze6x5dvvm
