I once clicked on a recipe that was pinned to a Pinterest board and it would not allow me to view it without registering for an account. They lost my eyeballs forever that day and I'm sure there's many others like me out there. Given their target revenue model was presumably ad/affiliate referral based, keeping potential consumers outside the wall made zero sense to me.

Same for me. I think this might be the actual reason they're losing out. The moment they started requiring to log in to view stuff discovered through Google anyway was the moment I stopped using them, even though I actually have an account.

I'd pay money to never see pinterest appear in another image search result again.

Search Google Images with "-site:pinterest.com"

You could even set a custom search engine keyword that searches Google Images with the above included automatically.
