Information harvesting
Google provides translated versions of the Advertising Policies Help Center, though they're not meant to change the content of the policies. The English version is the official language used to enforce Google Ads policies. To view this article in a different language, use the language dropdown at the bottom of the page.
The Google Ads policy on Information Harvesting will be updated around mid-March 2012. The more narrowly-tailored policy is intended to better protect users from sites whose primary purpose is to collect personal information. This includes but is not limited to sites offering free gifts or other incentives in exchange for personal information. The change will affect all countries, and the policy description will be updated to reflect this change.
