I would like to know if you could provide some descriptions or definitions for the types of Page Like Sources. The ones I see in the Facebook Platform are:
Restored Likes from Reactivated Accounts
In my report (table with Page Like Source, New Likes, Unlikes, Net Likes) with your connector I see some like "normal_unfan", "pagelike_deleter_for_deactivated_user", "si_system" and "banhamer".
Do you have a list of what your connector picks up and describes those sources?
you can get this data with "Page like source" as your dimension yes, but with that, you can for example use "New likes" as your metric to get that list of sources, otherwise if you use "Unlikes" metric in the same query, you'll receive other set of sources which are related to unlike metrics.
