As soon as I saw your review, I spoke with the team about making some modifications while we were continuing development on our newly redesigned plugin. We recently implemented some changes that should proactively address the exclusion issues you referenced. Our new data handler ingeniously provides us with more information about a page so that we can now identify when content is marked as private by WordPress.
And other than the Pages to Exclude section located under our plugin's General Website Settings panel, we also introduced a nifty new option on the Post/Page Edit/Compose screen, allowing you to filter specific content without the need to compile a list of URLs.
This provides more options to publishers for better recommendations management and for better handling on our end to identify posts that should be automatically filtered from the recommendations' rotation.
We hope you like the changes and appreciate that you took the time to focus our attention on this quirk. We're very happy that we found an elegant solution and that we've improved data handling for all publishers. Your feedback has been invaluable, and I hope you continue to utilize and enjoy our plugin.
We still have a lot of work planned as we continue to develop and evolve our products, including Shareaholic for WordPress, but are delighted to receive input from those who are using our plugin on their site. Thanks for being awesome!
