What's the other half?
It's not immediately apparent in the interface like it might have been in other communities using third-party software. (It would be really nice to access the feature using the kebab menu on the home page listing page, e.g. this:
.)
But at least on sh.itjust.works, you can access the feature through the Settings link:
... buried under your username menu, and then by clicking the 'Blocked' tab.

I hope that's helpful to someone else like me who wanted this feature too and didn't realize it existed!
EDIT: It's also actually a lot easier to find if you click into the community; there's a big ol' 'Block community' button:

heh bean funny
Subscribe to the communities you like, then switch to "Subscribed" view, just like on Reddit. The front page is what it is, an honest /r/all – on Reddit it was mostly porn, and after some retooling mostly low-effort meme subs. But that's exactly what "Subscribed" is there for!!
At least you're not advocating to harshly monitor/ban/disallow community creation, like some others already did, basically treating the whole instance like an uber-strict subreddit of its own.
Instead, it's easy: Subscribe. Then switch to Subscribed. If you want more communities, look at a list, or switch to All again.
I see nothing wrong with taking good, useful features from Reddit and making them available. It won't make Lemmy Reddit, it just makes Lemmy better.
thats why effort (github contribution) should be focused on lemmy web first. then when site is solid u can build apps on top of it, and u wouldnt need to think much of features later since web is already the inspiration
Just block them, there aren't many of these communities.
This feature already exists. When I block a community in an Android app and go to the website at sh.itjust.works, and look at my Preferences > Blocks, I see the community I just blocked in my app, even if they are on a remote instance.
So, I guess I don't understand the problem.
Then pick an instance that lets you do this? Why is this rocket science for some?
You're going from app to app and complain the app settings doesn't automatically follow you to the next app? Did I get that right?
How is an instance going to let you hide communities that would have to be an app feature
What are you talking about? You're using the same instance as me. If I can block communities. So can you.
If you're complaining that some app don't have that feature added to it. Then either improve it, write your own, submitt feedback to the developed, or pick another app.
Yeah of course you can block communities but you can't block entire instances which of course is what we're talking about.
Like diarrhea
thanks for using Leebra!

This is what the Block feature is for. Block the communities.
