These are interesting propositions.
I'm starting curation accounts myself. None of the "pay me for resteem sir" service stuff. Just a nice account stocked daily with curated posts around a specific topic I consider to be high quality.
Perhaps, this platform could end up being led by myriad tailored curation accounts like the one I'm starting. Again, unpaid curation accounts.
We could potentially solve the problem this way and stamp out the trash posts without going all commie and outlawing them or anything.
Like independent journals on the platform.
