Always best to file a ticket when you need an official staff response to a rule question, guys.
That said, the site rules reflect that we no longer have our own filter in place, but that members are expected to respect the use of filters on the site. We just don't have our own filter in place anymore, but encourage young or sensitive site members to use a filter on their end. So images still aren't allowed to use profanity, for the same reasons as before (e.g., for filtering purposes). I hope that clarifies.
