One day this fall I learned the hard way another addition of this rule I had never heard of. I went into AdWords to do my usual checks on one of my clients' accounts. I had seen volume drop down since the previous week and wanted to figure out what was going on. After digging I saw a lot of my ads were "suspended" due to landing page violations. The status notice pointed me to this link.
None of us on the PPC team had ever heard about how far this "information harvesting" rule could potentially be taken and result in negative (and not easy to fix) consequences. We have all checked our clients' domains and landing pages to make sure we are proactive with this policy moving forward. Has anyone ever run into any issues with AdWords privacy policies they weren't aware of? What were the results?
