Part of the problem is the lack of tools/functionality. Lemmy doesn’t allow for hiding images without the NSFW tag. It could/should function a lot more like mastodon in some ways in our opinion, allowing both the user to hide all images in their settings and having more specific CWs that could hide even the post image behind.
Yeah, sometimes they help to communicate with other players or the developers, seek out hints or bug reports, share cool things from the game or that you did in them, or talk to valve about features/bugs.
They would be a lot more useful if they were actually moderated but most game developers seem unable or unwilling to do it, and valve is the same, so what ends up happening is that it just becomes a breeding ground for fascism.
