Regarding the post title: Lemmy itself allows you to block communities, instances, and users. But it does not support filtering by keyword, e.g. filtering out any post with the word “platypus” in the title regardless of where it was posted or by whom. With help from the comments below, here are some third party Lemmy clients that have their own implementation of keyword filtering:

  • Boost
  • Connect
  • Eternity
  • Interstellar
  • Raccoon
  • Summit
  • Sync
  • Tesseract
  • Thunder
  • Voyager

Do NOT support keyword filtering:

  • Alexandrite
  • Jerboa
  • Lemmy UI
  • mlmym
  • Next
  • Photon
  • Quiblr

      I’ll never understand people who think they can change someone else’s mind on the internet while arguing about religion or politics

      I think you might have to respect that an anonymous forum on the internet where people regularly bicker and insult each other (atleast on politics posts) may not be everyone’s favourite way to interact with politics and news.

      I’ll never understand people who think reading that 6,251st column about how Biden is really totally definitely looking into legalizing cannabis constitutes “knowledge”
