Agree.

I think for an alternative to not depend 100% on growth on stakeholders, a cheap way would be very supportive of it.

Voting is a powerful tool but it is very subjective. What's good or what's bad is really difficult.

Is some photo without any written content bad content?

What if it some fashion thing or trend thing I don't understand and it receives 10k likes on other platforms?

What about a guide with 10k words about a game nobody plays?

For this, I think Reward tokens are always the better options, because "experts" in that particular topic can decide.

And because of this, onboarding would need an alternative way, that should be affordable.
