Why YSK: Certain topics are stressful and tend to spread all over the site, including to unrelated communities. Blocking communities can be overkill and ineffective, and likewise for blocking individual users.

To do so, open up the uBlock Origin dashboard, go to the ‘My filters’ tab, and add this filter:

lemmy.world##article.row:has-text(/word1|word2|word3|word4/i)

For example:

lemmy.world##article.row:has-text(/Trump|Elon|Musk|nazi/i)

Then apply the changes and reload any open tabs, and all posts which contain any of your filtered words will simply not show up.

You’ll have to change “lemmy.world” at the start to whatever your actual instance is. You can filter as many or as few words as you want, just keep the / at the start, the /i at the end, and separate words with | pipes. What’s actually being filtered is a case-insensitive regex, if you want to get fancy with it.

Here are equivalent filters for reddit and Ars Technica:

reddit.com##div.thing[data-context="listing"]:has-text(/word1|word2|word3|word4/i)
arstechnica.com##article:has-text(/word1|word2|word3|word4/i)

As a disclaimer, I made these myself, and I’m not particularly familiar with creating uBlock Origin filters. There may be better ways to do this. Also the reddit one is specific to old.reddit.com, and the lemmy filter is made to work with the default lemmy.world web UI and may not work on other UIs without tinkering.

Yes, I know I’m just hiding my head in the sand.

    I’m not sure I follow - the filter seems to work as-is to me. It allows posts on both the front page and the [email protected] to bypass the filter for me.

    To be clear, it’s not only applying to the title row - the article tag it targets contains the entire post as it appears in the post feed, including the title, community name, the person who submitted it, the timestamp, etc. So if anything there contains a filtered or whitelisted word it should trigger the filter.

    I wouldn’t have necessarily expected the whitelist filter to work directly on the leopards community page, since posts on community feeds don’t include the community name, but it works anyways because, it seems, there’s a hidden mod option in the HTML with the community name in it: <div class="modal-body text-center align-middle text-body">Are you sure you want to transfer [email protected] to [email protected]?</div>

      I did not do extensive testing, but what I did was directly visit the leopards at my face community and could see there were articles being blocked within there. This filter leaves the separator lines of the posts that have been removed, and I was surprised to see articles blocked when viewing that community directly. Maybe I just messed up my regex, but I wanted to unblock anything with leopard/leopards in it even if it wasn’t within that specific community just in case

      infosec.pub##article.row:has-text(/Trump|Elon|Musk|nazi|TikTok/i):not(:has-text(/leopard(s)?|schadenfreude|find out/i))

        Actually it seems to be a difference based on our instances - if I look at the community from infosec.pub then the bit of HTML I quoted above with the mod option isn’t present, and there’s no ‘leopard’, hidden or explicit, for the whitelist filter to find.

        As a note, the (s)? on your leopard isn’t needed - just ‘leopard’ will already match the ‘leopard’ part of ‘leopards’

        I don’t know how to fix this currently, but I’ll test out a bit more later to see if I can find anything that works well
