No support. One of the main faults of RSBot scripts [especially moneymaking ones] is that once you have it "leeched," the price crashes. Look at newts, for example. I am pretty well-respected on RSBot.org, and a bunch of people trust me to keep their scripts private. Having an independent section on Sythe, one of the largest RS Cheating forums, would increase the number of leeched scripts dramatically (since it is not going to be moderated by an RSBot.org mod), thus reducing the efficiency of RSBot as a whole.
It's a good idea, but I don't see what's wrong with just posting for help in the RS2 Cheating section. I don't want to see the great RSBot scripts get leeched like they did for Aryan scripts when Aryan sections were introduced into many, many other forums back in the day.
