Posts are being intercepted and appearing on sites one wouldn't expect to see them.
Google Posts Display on Third-Party Websites
When generating a Google Post, users will see a notice appear that informs them that their posts will appear on Google Services across the web. This means that third-party sites can share your business's Google posts on their sites.
Are people able to embed Google Posts on third-party sites? Is Google licensing the information out to MapQuest? These are both good questions. In the process of indexing these posts, it's clear that business's Google Posts are being intercepted, as they appear in places one wouldn't expect to encounter them.
