Our domain has been blocked by Facebook as spam – what can we do?

Hi HN,

Our domain http://mixlr.com has suddenly been blocked by Facebook.

This has led to sharing, log in and signup using Facebook to immediately stop working. (See below for message text)

We are a well-established business with hundreds of thousands of monthly active users and thousands of paying customers.

We are already losing customers and revenue, not to mention reputation. Does anybody have any Facebook contacts who could help to look into this?

Any help would be much appreciated.

Many thanks.

Rob
