We've veered dramatically from the GEO topic and I apologize, however your submissions could easily be interpreted to both advise and read that GEO and/or denial is ALWAYS detrimental to websites, and it's simply not so.
FWIW, most proxy servers utilize malformed User Agents and are easily defeated utilizing simple white-listing procedures.
I've (as do many other webmasters) extensive lists of proxy server, server farms and even colo's, most of which are long denied.
How you or any other visitor (human or otherwise), could make an authoritative determination confirming that they'd been denied based solely up on IP is beyond my comprehension.
In any event our mis-communication is not beneficial to this thread and I'll stop here.
