So, CC BY-NC is used for the default scripts, and its use seems to be heavily encouraged here. Well, it's a bad license choice, and you really ought to suggest and use a different license. There are two reasons.

The first reason you shouldn't use CC BY-NC is the licenses published by Creative Commons[1] are not designed to be used for software. They are designed for artistic works. Of particular interest, all of the Creative Commons licenses are incompatible with the GNU General Public License.

The second, and most important, reason you shouldn't use CC BY-NC is it's a proprietary, non-libre, closed-source license. I've read in a forum post from a couple years ago here CC BY-NC being described as "permissive", and that simply isn't the case. A permissive license is a free/libre and open source software license which has very few requirements. CC BY-NC forbids commercial use, and both the Free Software Definition and the Open Source Definition include the right to use and distribute the program commercially.

I don't know why a non-commercial license is being used and encouraged. My guess, though, is that it's some sort of misguided attempt to fight corporations. The proper way to do that is to use a copyleft license, such as the GNU General Public License. Non-commercial licenses stop poor individuals from making money and do absolutely nothing to corporations. Copyleft licenses, on the other hand, stop corporations from competing unfairly; even if you don't like them making money off of your program, all you have to do is incorporate their changes into your version and tell people that the paid version is a rip-off, because you're giving it to them gratis.

If you want to suggest permissive licenses, they should be the Apache License,[2] the Expat License (called the "MIT License" by the OSI),[3] or perhaps public domain dedication via CC0.[4][5] Or if you want to use copyleft, the best license choice is the GNU GPL.

Thank you for your advices. It'd be treated more seriously, if you would do it in a nicer manner, this 3 days after other strongly-worded mistakes.
I won't debate with you, the tone you used 2 times shows that you consider us too much inferior anyway. I probably won't let you instil more bad karma here.
But I'll let you anyway an note of why this was chosen : sexscripts are not mainly softwares or parts of it.
