Yesterday, i accidentally pinned some guy's pin to one of my boards (his pin was from my site and that's why i made that mistake). Anyways, now i can see his profile showing on my profile (pins from) . Obviously this happens when you pin something from another person, but i removed that pin basically after a couple of seconds after i pinned it (that pin from that guy), but i still can see that his profile is showing on that "pins from" place. Is this some bug with pinterest or maybe it takes more time to "get rid of" people from your profile who's pins you pinned but later removed them? Actually it's almost 24 hours and i still can see his profile on my page.
