I was inspired to go digging through the search engines too. If I've correctly sorted them out, the authors are quite competent game hackers and reverse engineering aficionados. Not clear if they even play the game much, as they seem to be in it mostly for the technical challenge and approval of their adoring users.This seems like you might have accessed a group that obtained the app, and not the authors. I applaud you for your digging - please keep going!
I would also note that as far as users go, it's mostly going to be script kiddie types posting on a publicly visible forum for game hacks. Obviously if organized groups and advanced PvPers want to use these tools there's nothing stopping them from downloading it and not bragging about it in public.
