If you keep your script to yourself then I wouldn't care if you pissed on it and topped it with whipped cream, but when it reaches others and they need some help with it, or when people that use bad scripting habits, help new impressionable scripters here or elsewhere, they're teaching someone else their crappy scripting habits. Also, just because "mIRC accept them, that all" doesn't make it a good thing, it just means it was left in to be compatible with old outdated scripts and bullheaded scripters who refuse to change their bad scripting habits.
