So funny story about that: I tried adding the N word to the profanity filter after you posted it and for whatever reason it wasn’t filtered. Maybe the filter only works on posts made after a word is added but I sure as shit wasn’t going to post an N bomb to test it out so I assumed the filter just didn’t work.
I think this is a reasonable assumption, i.e., that the filter rule is executed once when the post is initially submitted rather than every time a post is displayed. So I wouldn’t expect past posts to be impacted by a newly created rule.
I was looking at the profanity filter this morning for the first time (to make sure I knew how to do it if that’s what I ended up wanting to do), and I’m positive the n word was already there.
Right, I added it a few months ago when 6ix posted it and since his post remained unchanged I assumed I hadn’t added the word correctly or something but as TheDuker pointed out it makes sense that it only filters new posts.
