On version 0.19 you can block instances so that you don’t see any posts from that instance, instead of having to block communities one by one, you still see comments from users of that instance in other posts so it isn’t completely blocking the instance.
You can in the latest version of Lemmy that came out just a few days ago and is still not installed on most instances.
But how do you do it? Are there instructions?
I was searching to find an answer and came across this discussion, so for others asking: how to block an instance? (or alternatively: how to block instances? additional search terms to help find this: blocking instance on Lemmy? Lemmy instance blocking?)
If you’re on the web version of your Lemmy site/instance, click your username>settings>blocks, and this next part may depend on your display resolution or amount of blocked users/communities, but in any event: scroll down/look to the bottom left and if your instance is on the latest version of Lemmy there should be a new box labeled Block instance.
Click the menu/button to the right of the Block instance text and a search dropdown will appear. Type in or copy/paste the name of the instance you want to block, and if your site/instance has connected to it, it should show up in the search results. Click the result and wait a moment till the message “[instance name] blocked” appears. Depending on what your site/instance’s running on, general traffic, or other technical things, the time for that message appearing may vary.
Regardless, if you don’t see an immediate response, don’t be thrown off, it’s just taking some time.
p.s. giving a mention to ya @RainfallSonata@lemmy.world so you’ll see this reply too. Btw, like your name!
