Scrabulous? US and Canadian Facebook users were likely dismayed to find out this week that Scrabulous has been disabled. The region-specific lock likely has to do with Hasbro's license for all Scrabble video games, which is for US and Canada only (Mattel owns the rights for the rest of the world). In the interim, you can always play the official Scrabble Facebook app care of Electronic Arts, although it lacks the panache of the seemingly now-defunct Scrabulous.
