Disclaimer: I am just a random stranger on the internet who likes uBlock Origin, read a handy comment, and figured out how to press F12. I am by no means a webpage expert, and these changes may have unintended consequences

I wanted to bring more attention to @linuxFan@vlemmy.net's comment on how to block entire instances (not just specific communities on those instances) from your "all communities" feed, as well as add my own method to block them from the "list of communities" page.

This only works if you are using a web browser that supports uBlock Origin (so unfortunately, will not work on any of the mobile apps).

Firstly, install uBlock Origin if you haven't already. Then, click on the uBlock extension icon -> "Gears" (settings) icon -> My Filters. Per @linuxFan@vlemmy.net, add:

your.lemmy.instance.com##.post-listing:has-text(@theInstanceYouWantToBlock.com)

Then click "Apply Changes"

So if I were not interested in any of lemmynsfw.com's content, I would add:

lemmy.world##.post-listing:has-text(@lemmynsfw.com)

@linuxFan@vlemmy.net's ELI5 explanation:

lemmy.world## - only use this filter on this site

.post-listing - evaluate everything on the page with the class name post-listing

has-text(@lemmynsfw.com) - the text we want to filter. CASE SENSITIVE!

Similarly, if you want to filter entire instances out of the "list of communities" page, you would add:

your.lemmy.instance.com##tr:has-text(@theInstanceYouWantToBlock)

I believe the tr is table-responsive, which is the type of table displayed on the "list of communities" page. If there are other responsive tables on a different Lemmy page that I don't know about, it may affect those. Also, if Lemmy's website is updated, these filters may no longer work.

If someone knows of a better method of doing this, please chime in. But otherwise, enjoy!

Why YSK: some instances have many communities that are centered around topics people are not interested in, and instead of blocking all of those communities one by one, it is easier to just block the whole instance.

Edit: Note that this will remove posts if a blocked instance is listed ANYWHERE in the post body. I accidentally blocked my own post when I tested the lemmynsfw filter just now lol

You can also try out kbin as a Lemmy alternative, as it's fully federated with Lemmy and lets you block domains.

[-] rr7@lemmy.world 3 points 1 year ago

Thanks! Should be built in to easily block an entire instance

[-] UprisingVoltage@feddit.it 3 points 1 year ago

Very useful, thank you for sharing!

Also if someone isn't using ublock origin yet, please do! It's essential to browse the internet these days

[-] lemmy@lemmy.quad442.com 0 points 1 year ago

Pihole is great

[-] lozunn@kbin.social 1 points 1 year ago

Those two are not mutually exclusive, so both could be used at the same time.

[-] lemmy@lemmy.quad442.com 1 points 1 year ago

I'm not saying that can't be

uBlock Origin works on Firefox Beta for Android.

[-] sp6@lemmy.world 3 points 1 year ago* (last edited 1 year ago)

I think it works on non-beta Android Firefox too. I just meant stuff like Jerboa, Mlem, etc; mobile apps you download from an app store.

[-] Dick_Justice@lemmy.world 1 points 1 year ago

I wonder if something like this could be used to exclude Reddit result from search engine pages.

[-] GroggyKon@lemmy.world 2 points 1 year ago

Bless your soul my child. I can now get rid of lemmygrad.

[-] Holyginz@lemmy.world 1 points 1 year ago

What's wrong with lemmygrad? Serious question since I'm out of the loop.

[-] GroggyKon@lemmy.world 0 points 1 year ago

It's essentially a community that promotes left wing extremist ideologies and is very much in favour of authoritarians who don't like democracy. Lots of hate for the west, lots of whataboutisms and lots of love for Putin and Xi and lots of excuses for the invasion of Ukraine and the Uyghur genocide. I'm left leaning but they have more in common with fascists than anything else.

Great post! If it works with unblock origin then it also works with Firefox on Android.

What if i just want to block any post from any community from any instance with the word 'trump' in the title, is there a way to do that?

[-] sp6@lemmy.world 1 points 1 year ago

Sort of. Change has-text(@TheInstanceYouWantToBlock) to has-text(ThePhraseYouWantToBlock).

Just note that:

The filter is case-sensitive, and
This will block the post if the phrase is anywhere in the post. So even if the phrase isn't in the title, but is in the post's text body, the OP's username, the community name, etc, it will still be blocked. So blocking "trump" could accidentally block a playingcards post that has "trump card" somewhere in the post body.

What does going to Settings > Blocks > Block Community do? Doesn't that work?

[-] sp6@lemmy.world 2 points 1 year ago

That blocks a single community on an instance, not the whole instance. So take this community, youshouldknow@lemmy.world. You can block youshouldknow (the community), but you cannot block all of lemmy.world (the instance). The method in my post allows you to block entire instances.

[-] TerabyteRex@kbin.social 0 points 1 year ago

how do i save this post on kbin?

[-] grizzly_dw@kbin.social 1 points 1 year ago

FYI, Kbin lets you block entire domains natively, though in a roundabout way.

Looks like you're using kbin.social, so you would put https://kbin.social/d/domain_you_want_to_block in your address bar, which brings up that entire instance (including lemmy instances) as a magazine. Then just block in on the right, the same way you would block a community/magazine.

You can check which domains you've blocked in your settings. Go to Settings > Blocked > Domains.
