Just remembered Ublock Origin filters also work nice with fediverse sites, although I would prefer to completely purge posts with links I avoid.

But for those curious, here’s an example filter I just cooked:
lemm.ee##a[class=“fst-italic link-dark link-opacity-75 link-opacity-100-hover”]:has-text(here_goes_the_domain_as_displayed_under_the_post_title):upward(div[class=“post-listing mt-2”])

So as an hypothetical example, if for some reason I have a problem with the sh.itjust.works instance, I could make this: lemm.ee##a[class=“fst-italic link-dark link-opacity-75 link-opacity-100-hover”]:has-text(sh.itjust.works):upward(div[class=“post-listing mt-2”])

And it ends up looking like the attached image.
