From Pacific Epoch :

Shanda (Nasdaq: SNDA) subsidiary Aurora Technology has frozen game accounts of male players who chose to play female in-game characters in its in-house developed MMORPG King of the World, reports 17173. Aurora stipulates that only female gamers can play female characters in the game, and it requires gamers who chose female characters to prove their biological sex with a webcam, according to the report.

Though Red Sox starter Curt Schilling was unavailable for comment, I’ll just presume he approves of the above measure.
