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.
Deleting an account is just what it sounds like - the user no longer exists and their posts and PMs are deleted, as well. If they started a thread, that entire thread is deleted, as well.
I have recently granted these requests, just because it seems like the kind thing to do. But it’s actually a pain in the ass, depending on how many posts the user has and how many topics they’ve started. It also really disrupts the user experience here, because deleting posts from within a topic can make it unreadable. And deleting entire topics is terrible, obviously.
So far, I’ve been manually looking up any topics created by to-be-deleted users and changing ownership of those topics to a fake user @ThreadStarter so the topic isn’t deleted when the user is. But that is a one-at-a-time manual process that is an enormous pain for anyone with more than like 3 topics.
Anonymizing accounts, which is both easier and results in a better user experience for everyone else is FAR better.
