Edit: The above Connect filter only works for title posts. It doesn’t seem to filter comments or community names.
I mention this only because of some questions here and how people are going to the effort to censor out comments on this post.
Where is that filter?
It depends on your Lemmy client. I only use Connect, so I can’t tell you where it is in other apps, or if other apps even have it. (Settings -> Filters)
Connect is a simple app and has stabilized quite well over the last few months. Instance, community and word filters have been in the app since I started using it. (Instance filters were implemented long before Lemmy had that as a core feature.)
TBH, Connect was about as close to RIF as I could find at the time and it’s been great. (It’s had its share of bugs, but most are squashed now.)
