Getting back blurred images on SWF prompts using API

So I recently just setup the API for a project and am very excited. Occasionally while testing with an innocent "SWF" prompt like "clown in space eating spaghetti" I'm getting back blurred images. Even though I have the code functionality to detect the NSFW filter like detailed in the instructions it's not being triggered. Also not seeing anything back in the API response. Any advice?
