word or phrase in title (like kardashian)
This is currently available in Mlem under Settings -> Safety & Filtering -> Keyword Filters :)
word in link source (like dailymail)
We do not currently offer this feature. In Lemmy 1.0, the Lemmy developers have implemented a keyword blocking system on the backend that includes this.
word in sublemmy (like meme) word in tag (like #sports)
This isn’t currently possible through Mlem or through Lemmy. I’ll create issues on our GitHub to keep track of these ideas 👍
