copyright licensing
Can you take an existing copy right licenses and tweak it?
<p>I'm interested in putting some stuff up on DiviantArt, and while I like the license options, I would like to restrict them a bit. Namely I'd like to prevent copies or derivatives from appearing places that I haven't also published them. If I put something on DA, otherSite.com, and YAsite.com then those are the only three places I wish to allow derivative works or copies to be posted. At the same time, I wish to be able to post my work anywhere I wish. Furthermore, if by some strange chance I come into a situation where I can make money off of my work, I would like to do so, while disallowing derivative works to be sold for money (but still allowed for non-profit). Can I say something like ``CC BY-NC-SA 4.0 except for X-Y-Z provisions&quot;?</p>
<p>Looking this up, I found that the GPL (GNU Public License) may be modified, but I'm not interested in GPL, rather a modified Creative Commons license.</p>
<p>edit: To be more explicit, I want to say the following</p>
<blockquote>
<p>This is work may be lisenced as per the CC BY-NC-SA 4.0 with the fallowing alterations:</p>
<p>(1) $myName, the original IP creator, may collect monetary compensation of his work. This does not imply that the original IP creator may monetize derivative works, nor that derivative works may be monetized by their creators.</p>
<p>(2) Distribution of copies and derivative works is restricted to those methods/places/whatever that the original has also used.</p>
</blockquote>
<p>I'm thinking something like that, but not necessarily that.</p>

<p>It depends on the license that you are using as your basis. The SE terms of service includes a modification of CC-BY along the lines of your "except that" example. There have a mechanism, called "<a href="https://wiki.creativecommons.org/wiki/CCPlus" rel="nofollow noreferrer">CCPlus</a>", that officially allows you to grand all of the rights of a license <em>plus</em> specified others (you can't retract a right, there is no "CCMinus"). CC explicitly grants <a href="https://creativecommons.org/faq/#can-i-change-the-license-terms-or-conditions" rel="nofollow noreferrer">permission to modify the license</a>, as long as you don't call it a CC license (you can mention that it is based on a CC license). They state "CC does not assert copyright in the text of its licenses, so you are permitted to modify the text as long as you do not use the CC marks to describe it".</p>

<p>It is a separate question whether you should use the vague word "monetize" in a legal document. Your lawyer would advise you why that is so, and would advise you whether your re-writing was legally coherent. Since you are retracting rights you can't use CCPlus.</p>
