Lol, I can say that I fell for it. Well, in a positive way. I was actually happy that China got "un-blocked." At least I wasn't one of those people who took this stuff really seriously and bitched about it. They uber failed.
But of course, it just so happened that Newgrounds gets un-blocked on April 1st. I almost believed this was true, right until I saw the level icons, the review filter (it would change the wording so that it sounded "Asian" lol), and thread mood smilies that all had the stereotypical squinted eyes. If you were to actually make the site approvable to the Chinese for their people to visit, you wouldn't have put all those extra little things that were pretty much inappropriate. So all the people who took this the wrong way and really bitched about it are totally blind. If only they actually looked at all the things that were out of place.. the fact that it was on April 1st should've been the biggest hint lol.
But good job on the prank. I pretty much woke up my parents laughing at all the little changes I noticed. Good fun :D
