Thumbs up for the hacking part!
Regarding your karma - 1001 and 4 fans seems suspicious, but is a normal consequence by getting the gorilla too quickly, because then you don't interact enough with fellow DJs / listeners and build your "network". I got it in 4 days without cheating.. but I spent way too much time in coding soundtrack (just repeating what everyone else was playing) and felt that way after:
< 1000 : I NEED bouncer gorilla !!
> 1000 : the gorilla is ridiculous.. I take the geeky red ape!
it sounds like they could avoid user code accessing the room manager by wrapping it in an anonymous function, so their code wouldn't be accessible to other javascript.
however, this analysis isn't really complete without looking at the http traffic that accompanied these script calls.
this would make it a bit more difficult, but it's hardly that simple. an easy way around this would be to make sure turntable loads your modified scripts instead of their own.
