Yes, I know that's the theory, Rodrigo. And I've heard several boosters state it is their practice. But as a newer writer, until you have maybe 4K followers and 100+ subscribers (ballpark figure), which will take maybe 2 years, they simply won't find your stuff.
When I have a piece boosted by a pub, it gets its 500+ views and 300+ reads. But anything that isn't boosted is seen by no one but a smaller hardcore of writer/readers I have closer contact with. Maybe 2 or 3 'random' others. I could have 200 clappers for a boosted piece, but the algorithm seems not to pick up on that, because I never see them again, unless they subscribe. I 'know' this because if I publish something similar a week later, with the same tags and in the same pub, it's crickets and tumbleweed.
So lone wolf or pub-tied nommers are unlikely to see my pieces until some time in late 2025...
Buster even suggested (to someone else) 'reaching out to' nominating editors at other pubs. Is that really how they want this to work? Apples for teacher? And people like Thomas Gaudex at Scribe openly saying 'Hey, I'm a nommer - here's my Kofi account. Oh, no obligation to pay up to get boosted, you understand'. And nothing done despite it having been flagged up to Medium management months ago.
So I would say that in practice, to get boosted, you do need to submit to nomming pubs quite regularly, which is one reason why Medium occasionally brings out a new list of the illuminati.
