If Im correct, Kong is the only actual place it is at.
The game is VERY successful, that is true, however, take a look at the amount of people that have been on the forums today. If I am looking at the right place, then that is 128 people. Honestly, it really isnt that large of a group. The forum has a ton of members, however, who knows, maybe the next JMDT is on Newgrounds. Maybe Theres another puppychow on Armorgames?
Heres the real question, I to a certain degree, understand that you wont want a site with questionable content on it to be displaying your game, however, why not spread the game to many other sites? Is more people, despite their maturity level, really a bad thing? The mods are active and are more than willing to ban/mute people. If they come here, the spam wont be ignored like on newgrounds.
One final point, if it does go on more sites than just Kong, then he wont get as much revenue from kong. This is probably one thing that is being considered.
