I'm a member of a Discord server like that. It's named Past Gen. This is the server's own introduction:
Welcome to Past Gen Gaming! We're a community of generally older, but mainly patient and relaxed gamers. There is no age requirement to join us, just the mindset. We won't tolerate elitism, toxicity, nor any form of hatred. A lot of us don't have a lot of free time, so when we do, we like it to be a good time. So sit back, relax, and let's play some games together.
Just let me know if you'd like an invitation link. If so, I would DM it to you instead of posting it publicly.
I've been using the Razer Wolverine Tournament Edition for years, after wearing out a regular Xbox controller and returning the Xbox Elite controller because I didn't like the design. It's held up well. Looks like the latest version has hall effect sticks too.
Mastodon is a huge part of the Fediverse. It allows you to control who can follow you (you can set it to prompt you to approve each new follower). You can make your posts visible to your followers only. Each post you make has a visibility option, and you can set it to followers-only by default.
Protective DNS, when set up with a DNS provider that blocks known ad / tracking domains, would help with that. NextDNS, Control-D, and Mullvad all offer this service, for example.
Done!
