If you want to find screenfuls of Pinterest spam pins, here’s a quick way to do it: go to http://pinterest.com/source/amzn.to/
(This was suggested in a great thread about the Pinterest spammer on the Hacker News startup forum.)
Pinterest’s special ‘source’ URLs show all the pins from a particular domain, in this case from Amazon’s amzn.to URL shortener.
Right now, almost everything on this page is spam, using the Amazon affiliate ID of numanumaman-20.
No doubt there are spam links to other sites, too. Or if not, there will be soon. But for now, Amazon.com, with its wide range of pinnable products is the most obvious site for a spammer to send people to.
