The forks could just change their name, so they're more easily found. For example mRemote got pretty much abandoned, so mRemoteNG got created.
Or people give forks better names. For example, I've forked some dotnet6 project, and called the fork {project}-dotnet8 - then when people look thought the fork list on github, it's not 20 forks all with the same name
If you have a C# project that I can help with, as you mentioned, would be cool. I don't have that much experience with Rust, besides getting the Lemmy backend to compile.
I have experience working on the Lemmy APIs; I was trying to make my own front-end lol: https://blamm.it (Because mlmym requires a running Go Backend Proxy, to proxy requests between the Front-end -> Go Backend -> Lemmy Backend) - (which could easily be running maliciously, since you can't verify the hosted Go Backend isn't modified to log requests or something) - (And it's slow)
Hosting wise I have loads of experience with AWS... though not sure where you're hosting
