Unfortunately they seemed to have pulled the plug on business use so you'd need to create a "home" account in order to take advantage of their categorization-based filtering as well as their fuzzy matching; don't think it's regex capable though, but the categorization is pretty solid so you may not need to create "*.facebook.com" -- instead, just check off "social networking".
