FaceBook Page Comment Blocked?

[sand]

OK, this has never happened. For some reason whenever I try to comment of a page's picture or status, its says this:
ACTION BLOCKED
You have been temporarily blocked from performing this action.
If you think you're seeing this by mistake, please let us know.

Then I press the cancel button because it's the only button on the popup. Then it leads me to this:

CONFORMATION REQUIRED
A confirmation is required before you can proceed.

This has been on forever and I asked the Facebook help thing and they say they can't do anything about it. Someone help!
