How do you block or prevent "pins picked for you" on Pinterest?

I don’t want stuff picked for me. I can pick my own stuff, thank you very much. That’s the whole idea behind Pinterest, isn’t it? To pick stuff that you like. Pretty much every pin that has been picked for me, by God knows who, contains meat, meat, and more meat. Clearly, I would never pick those things and I want those pins to go away. So far, I’ve just been hiding them all, individually as they pop up, but that’s getting tiresome and tedious.

I’ve tried pushing the button (on the pin itself) that says “hide all pins inspired by” my own boards. That hasn’t helped at all. The personalization (which I assumed created these pins for me, against my will) is turned off.

How do I make it stop???
