No, but the suggested pins when I log on really annoy me.
do you unfollow people/boards? it really helps.
it was straight up jacked for me for a few days. it kept crashing and i couldn't pin anything.
That's how I feel it is for me right now, the option to re-pin isn't even there when I click on a pin. And, I'll browse through a particular section (like weddings or women's fashion) and it runs out of pins really early without the capability of loading more.
