This UA has been around for several years, mentioned here at WW in several forums, often associated with questionable behavior.
The URL in the UA string is invalid, possibly just an oversight. However the several listings in the SERP are also invalid. It seems the only accessible web presence is facebook.com/thefind. This may explain why the IP address above belongs to FB.
