Stats based on Access Token?

My app stores the Facebook Access Token for offline use. The main purpose of the开发者_JS百科 app is to allow users to automatically posts on the walls of people within a specified number of days of their friends birthday.

My app has been blocked by Facebook due to spam (some users are sending marketing messages to their friends instead of using the app for it's purpose).

I want to find out who those users are and block their access to my application. The only problem is that my Facebook App has a few hundred access tokens (one for each user of my application). The insights dashboard does not provide me with stats per access token. I need to find out which of my users are getting their wall posts reported as spam.

Is there any way of doing this?

After appealing, Facebook has unblocked my application but I don't want it to happen again. As far as I can tell, I can find out the number of people who have reported the wall posts as spam...but I don't know which access token made those posts...and hence don't know which of my users is posting spam messages.

It's not Facebook job to keep track of your application internal activities. You should be logging every activity, at least posts ids returned when someone posts anything on their friends' wall.

And one more time... you DON'T need the offline_access permission to publish something when the user is offline!
