As far as I can tell your blacklist looks fine. Does it work when you try to search rating:e?
If your blacklist is working at all, you may just be seeing explicit content due to it not being tagged properly. Check the tags on the post to make sure they are properly tagged, or if they are using tags that aren't actually in your blacklist.
i have checked this myselve. i can search for the same tag i have in my blacklist (copy pasted over) and see the posts
