I've read quite a few post with similar issues where other businesses experienced the same issue along the Pinterest Crawlers that crash web site as they send hundreds of thousands queries in a minute. Has anyone had a real answer from the support other than the one I just had after 2 weeks of chasing them:

Hello, I have been experiencing this drop for about 3 months and I have created many support requests about it, but I did not get a response from pinterest like you. We don't know what the problem is and no one is giving an explanation.
