Yeah, it's true that the second time around Pinterest might have less patience for HP. I'm thinking that for everyone who hasn't read or doesn't know the "invisible rules" of not spamming, it might be better to restrict pins per month so that everyone has to do it.
I, for example, did not know that promoting your own stuff was an issue, even in abundance (though I did pin lots of others besides myself, didn't know it was a 10:1 ratio until an hour ago). I should have known. But no one told me, until I researched it. Restricting pins would fix this for anyone like myself who did not know the rules.
HP team, take note of suggestions, they might come in handy!!!
