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 @[email protected]’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 @[email protected], 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)

@[email protected]’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
