How do I delete my Google+ posts on Topsy?
Topsy automatically crawls and indexes all public Google+ posts. This means that your public posts on Google+ will get included in our index. If you want your current posts deleted, please contact us.
However, going forward, if you post on your Google+ streams publicly, they will likely show up on Topsy again. We recommend you only share things within your circles if you don’t want this to happen.
