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
Comment anything I have missed or mistakes I made
Many lemmy apps do though. I use the feature on voyager
Summit even supports regex if you want to get fancy :D
And will also let you block entire instances, like say hexbear.
Instance blocking has been able on vanilla Lemmy for a while, no need for this at the client level
Instance blocking despite all the promises turns out to be mostly a lie, and has actually gotten weaker with time. Although we were told to wait and then this feature would solve our personal defederation needs, the opposite turned out to be the case. On 0.19.3 it at least used to prevent notifications (confusingly enough), then on 0.19.5 it no longer does so.
I still see every comment, they can reply to me, I can reply to them, and the only thing it ends up doing is hide communities - including auto-name-expansion with the exclamation mark. I wanted an actual “block” of an “instance”, but apparently I must move to another instance to get that:-(.
Voyager number one yeeeee
