You think the gaming community doesn’t have CS gamers?

See my other comment where I do just what you say you can’t:

For example I wanted to know about HaikuOS. It’s an open source OS. There’s no community for it but I know Linux users are the most likely to know about it and the Linux community is huge.

So I asked in c/Linux and found users of the OS.

If I didn’t get a response I’d ask in c/AskLemmy

I’ve done the same with anime and games.
