Why would he be protecting any program other than Simba?
I don't understand why you guys are thinking that Simba is 'sooo' detectable, since when does anyone listen to the propaganda Jagex says about bots? Obviously it wasn't the easiest to get rid of, as it's been there much longer than rsbuddy or powerbot or whatever and it's still standing regardless about what Jagex said. Who cares if they have a reflection bot-maker working for them?
Why isn't it detectable? Well, for starters there's no editing of the client whatsoever. Plus there was a lot less random-ness in most javabot scripts as far as I could tell, I noticed they tended to click on the same or close to exact same tile every time and similar spots on objects (obviously it could be randomized and made better by scripters in Java bots, same goes for Simba).
There's no valid reason as to why the color scripts at SRL would be more detectable except for maybe random solving, which it just logs out for if it can't solve it anyways. If you're that worried use scripts created by SRL members+ as they have all had to prove they can make a properly functioning script.
