Isn't the one HTML5 game they have broken as hell? I remember when it first came out AAA's revenge something or other, a few people got avatars and then it stopped working forever? As far as cheating on it, it was very easy to manipulate the script for the game. I don't know about score-sending, but as far as cheating beyond that, it's pretty easy if they are unobfuscated.
I sometimes think that while these Q&A's have best intentions at heart, they are mostly for show to make the masses think they're doing things. I guess I've just grown cynical over the years with the great changes and improvements of TNT.
