Changes to Facebook's automated platform monitoring system resulted in many apps suddenly being shut down without warning at the end of last week. Why has this happened and what should developers do about it?

The Facebook Developers Forum saw a burst of activity on 26 June with devs looking for answers as to why their apps had suddenly been banned from Facebook.

The reason, as explained on All Facebook is that a stronger anti-spam enforcement system had been rolled out by Facebook in response to a spike in amount of application spam end users had complained about on  feeds and on walls. However this was done without any warning and caught a number of innocent and popular apps in its rather heavy-handed trawl.

Developers who want their apps reinstated should fill in the Disabled application appeal form. A statement from Facebook also notes:

"We're working on new analytics to help developers better monitor negative user feedback to prevent a spike like this in the future."

However it doesn't offer anything by way of apology and seems guilty of poor communication with its developer community.
