@nprofile1q... There's words involved, I edited the post to put a coffee mug in, and on the thread you see a mug, but edit mode you see this

So is this person perhaps using an emoji that gets blocked or ignored because of your filter list?

@nprofile1q... Aren't emojis effectively :<keyword>: or something to that effect despite what we see? If that's the case I imagine that whatever emoji they're using has a keyword that you're filtering.
