We removed the “report unliker” button from the History pages because people were reporting EVERYONE instead of just unlikers which defeated the purpose of the button in the first place.
Luckily we’ve come up with a new way to track unlikers and it seems to be working very well! It’s automatic and has caught most unlikers within their first 10 unlikers (sometimes within the first 5).
We’ve also added the number of Likes your page currently has on Facebook to the “[name] liked your page” history updates. You can now track and see who became like #531 for example.
