Ask HN: Facebook Says Composer Data Unavailable – Domain Blocked on FB

For my site www.raptorsrepublic.com, I'm getting this error for the last month every time a link to the domain is posted.

We are blocked across Facebook with no links being allowed.

I've contacted Facebook a number of times to get more info on this, but no response at all. I only get an automated message saying:

"We received your report and appreciate your patience as we work to fix technical problems on Facebook. Though we can't update everyone who submits a report, we're using your feedback to improve the Facebook experience for everyone."

Obviously, this doesn't help or give an explanation. I'm dying to talk to a human being at Facebook, does anyone here know how to resolve this, or even have an idea of what my options here are?

Thank you.
