answer:It looks like the only thing you can do is contact them. On the portion of their FAQ where it’s talking about “Promoted Pins”, they say if there are any you don’ like and you want ones better tailored to you to just let them know with some feedback. On the page where you submit the feedback, there’s an option you can click that says “Picked for You Pins”, so I’m guessing it’s similar. I think all you’d have to do is leave a comment that said something like “I’m not at all interested in seeing any kind of Pins that contain meat.” and they should fix the issue for you. Or try to, at least.
