Probably because KH fanart sites are all taken down by Disney and Squeenix! I swear, every single one of those sites is hidden behind fifty passwords and trick questions in Japanese. (I haven't the slightest clue why the million DevART guys are left alone, but I'm VERY grateful for it.)

To say they're heavily guarded is an understatement. I guess people are afraid that if the Japanese fanartist's links are reveiled, their sites'll be taken down.
