Answer 1

No need to talk to "passers-by", you'll just lose a lot of time.
Write an article on Habré, it will be more effective.
The main feature of the hackathon is locality. People participate to get new experiences, and isolation in some new place for the duration of the hackathon "frees" a person from routine household activities, from the main work, from "sleeping", from the usual routine.
An online hackathon is kind of an oxymoron. So that it does not turn into a "zilch", you need to somehow attract and somehow keep people in it. It is not simple. It is not enough just to do everything as usual, but online.
You will have to find either a cool catchy topic paired with a very active and large community, or a loud and resonant occasion that will support excitement and engagement.
For a more fruitful search for an answer to your question, it would be nice to know more details. What a topic, what a stack of technologies, what a goal...
I'm thinking about the concept of "endless hackathon".
This is such a platform for publishing ideas, teams and projects for discussion and collaboration. Someone will say: "Why?! There is a github, gitlab, kickstarter and others! There you can create a project page, discuss features, accept feature requests, fork, do reviews ..."
The essence of the "Endless Hackathon" is that it is primary it is a collaboration of discussion and planning, not coding.
On the site, it would be possible to start a project, issue its card (for effective search), set up donations for crowdfunding, link a repository (possibly made according to a template).
There is an IDE and gitgub for working with the code, there is a zoom for communication, but there is no single crystallization point where you can look for projects, like-minded people and ideas.

Answer 2

assemble a hackathon in which all participants will have equal percentages of the final product.

I had no idea what this word meant before...
But then... I realized...
Now this is a fashionable line of business: the materialization of income from "air" with the help of tests and competitions.
I usually distribute to all hackathon participants their own, jointly made product, absolutely free.
This is their work, their authorship, their project.
I am just an organizer.
