this is a shared IP address employed by the Opera Mini java application available for mobile devices. AFAIK Opera Mini runs all pages through their own proxy servers. Hence, this is a shared ip address and you folks who so vehemently desire to comment upon/post warnings to the talk page probably don't realize that these messages are being sent to dozens if not hundreds of individual uses. BAN THIS IP ADDRESS. Contact Opera and ask them for a list of all the proxies that are employed by Opera Mini 3.0+

Good day sirs (I have never made edits via this IP but thought I would illuminate you all to what is going on). In closing: perma-ban this IP, wikipedia is impossible to edit via mobile web anyway. 68.171.231.21
