Yes, I can. But you need much more to accomplish this

1. You need reach: are there any mods/admins that would feel ok with vouching for your abilities? And preferably have info about your proposal stickied on a bunch of communities where it could reach people open to chip in?
2. You need to convince those you reach that you’re not a Nigerian Prince. Mod/Admin saying you’re legit could help with it but maybe there’s something more you could do to convince the public?
   Maybe I simply don’t know who you are, maybe in reality you are second in command after Dessalines. But either you are a random dev saying “I can do that” - in this case you need to somehow convince others that you really can. Or you are not recognised for your work - in this case you need to point us to what tie you to. I saw the fedi project on your GitHub so you probably can code (I’m not going to be auditing your project in order to asses your skills, sorry). But are you just a dreamer or are you serious?
   I’m sorry if what I’m saying sounds harsh. I just feel that how you are coming through to the other side gets lost in translation here
3. GitHub is not the most popular support medium. Why not also have Patreon/Koffi/OpenCollective/etc? Many will chip in easier if they’re already present on the platform

There are other communities too

Maybe I’m going to do something, maybe I’m not. Why the demanding tone?

I also think that grassroots economy would work better for many things. But we’re not there, the world doesn’t work like that ATM. Wish for 10% of people to contribute is very optimistic IMO.
You need much wider spread, and for me (for example) your tool is the only thing that gives you any credibility. If there are others like me, you might be missing clout for a call to support like that to simply just work

24h for people to react to a comment in some post?

I think you under-advertised your proposal
