I agree with what Sub said, the people who get banned are generally a salty vocal minority.
Botting for most people is a for profit venture, so to an extent everyone is a competitor. Generally people will help and try and push them in the right direction when the blame the client. If it were the client a lot of these high quality scripters wouldn't even bother with Dreambot. The quality of this client is what attracts these scripters.
That being said no one is going to hand a salty person a script with low ban rates and decent profit just to prove the client isn't the issue lol. Botting rewards those with either deep pockets who can afford quality scripts, people with good problem solving and logic skills (our scripters), and those who just get lucky.
