Domain banned by Facebook

I registered My domain "www.3rbpro.com" at 31/5/2014 and set up WP blog on it, For some reason my domain was banned from Facebook. So when I try to post a link from my domain in Facebook I get this notice: https://www.dropbox.com/s/y2bnlaaqm4ieiua/Screenshot%202014-... I've tried contacting Facebook via the form but they don't answer me. Is there any way of knowing what caused this and is there a way to fix this because it's crucial to my business.
