Third, I do believe there are third party clients (lemmy apps made by others) that have a word filter feature which allow you to automatically hide post and comments which contain certain keywords. (I think Voyager has that. Download mobile app here. Use the site version of the app here. Keep in mind that it uses lemm.ee as its default instance.)
!newtolemmy@lemmy.ca has a pinned post with a guide on how to block keywords
Plenty of investigation going on !nicole@feddit.org
