That's one of the bugs.

And I still know tonnes of people, especially at my workplace, that drive SUVs with "Fuck you Greta" stickers and that complain about everything and anything that is even remotely related to climate change.

From personal experience I can say that it runs very well at high settings! Nearly level 20 now and haven’t had any issues yet.

Ideally, I think no one instance should have a million users to begin with.

There's a homelab community, https://infosec.pub/c/homelab@lemmy.ml

Thank you for your answer! :-) I am sorry for not seeing that post!

I run a PeerTube instance and the amount of people that try following my instance with exactly THAT type of content is... astonishing. It just seems like no PeerTube instance is properly moderated.

Fallout mostly. It's all just so grey and boring and not fun at all. If I want to see a wasteland I can just go outside /s

There isn't really an alternative to Mlem at present, so the only thing you can do is to make due with it for now and / or use the website. I mainly use the website at present because Mlem doesn't have a compact mode.

For that to happen, I believe that interacting with people from other instances and moving your community and account from one instance to another have to become possible / easier.

At present, people flock to the instances with most users as those often have more local content (local content is generally easier to find than federated content) and they often have a smaller risk of shutting down. If I create a community on a smaller instance, the chance of it being found and interacted with are also much smaller than if it had been created on a bigger instance (because of, as I said, local content being user to find).

Sure, I can create an account on myfirstlemmyinstance.com (example URL, not an actual instance) with 10 users, but if my instance decides to shut down, my community of, say, 500 users will now have to move somewhere else and all old content will be deleted.

What problems are you facing on the website exactly? I'm just accessing my instance's website via Safari and it works pretty okay. I'd just recommend opening threads in a new tab, perhaps.
