Do you know any good adult webmaster forums?

Webmaster Tools - Structured Data 100% drop. Many people with same issue, nobody seems to understand what might have caused it. Any ideas?

• WMT shows a significant drop in structured data markup on June 7th, steep incline by June 21st. Now the same thing happened on August 9th, with no signs of recovery. Lost 45% of our search traffic. There are many people with the same problem, and nobody seems to know what caused it. Here are a few links to some forums: http://productforums.google.com/forum/#!topic/webmasters/8ncTam-yNjs, http://productforums.google.com/forum/#!topic/webmasters/h2iLOU_18DY, http://productforums.google.com/forum/#!topic/webmasters/bBDNUIMWWos, http://www.webmasterworld.com/google/4585591.htm. On our end we see a 100% drop in breadcrumbs and a 100% drop in hcards leading to a 45% search traffic drop. Any ideas why might have happened and how to fix this?
