Yes, I use a uBlock Origin filter that looks like this:

lemmy.ml##div.mt-2.post-listing:has(.d-sm-block.d-none>.post-container.row>.flex-grow-1.col>.row>.flex-grow-1.col>.post-title:has-text(/trump|elon|musk|biden|kamala/i))

You'll need to modify the domain at the start (replace lemmy.ml with your instance hostname) and then change the keywords at the end with whatever keywords you want to exclude.

To use it:

• click the uBO icon and then the gear (settings) icon
• click on the My Filters tab
• make sure that "Enable My Custom Filters" is checked
• paste the filter into the text area below
• press the "Apply Changes" button

Browse with an app that lets you filter keywords. Boost is good.

You bet! Voyager is an excellent app with filters in the Settings -> General section.

I’ve blocked trump, vance, and elon and my feed has gotten 1000% better.

It can be done using some arcane browser extensions or in apps like Voyager.

There was a TIL post last week on similar topic. The OP shared a browser solution they found: https://lemmy.world/post/21852842

I did this on Firefox, but I suspect it may work in other browers too.

1. Install the Violentmonkey extension. Tampermonkey or Greasemonkey will also do.
2. Install the Lemmy tools script.
3. Browse to Lemmy
4. Click on the screw driver icon on the LemmyTools bar that is now visible on the Lemmy page.
5. Scroll down and check the box next to "Content Blocking"
6. Add your block words in the "Add filters seperated by commas." box. I typed "Trump, Vance" Voila!

Filters. I use Voyager and I have filters blocking pilotical crap. It works quite nicely.

I think this is only possible through apps at the moment, like Voyager. Although there has been recent talk on GitHub, they acknowledge it will take a while before it's implemented.

Others have talked about mobile apps, but if you are on a browser, check out Lemmytools. It also adds filter by keyword to Lemmy.

This is supported in PieFed by default, in case you're interested in checking out other Lemmy-compatible software.

My filters kept me sane through American election season.

Look at only communities you're subscribed to, and unsubscribe from all where talking about the topics you don't like is allowed.

At some point this might become part of the software, but for now it has to be an external filter. Some apps as mentioned, and when Kbin was starting off some users got together to create addons for it, some that would actively filter with varying success. The idea is simple, making it work well is not. There also might be addons for browsers that can help filter things, but they would need to be set up to find certain properties of the message code that are around that keyword and remove them selectively to filter cleanly.
