Do not share without permission
This either conflicts with the terms of the Creative Commons license you specified or is nullified by them and is definitely a violation of their trademark policy.
All general public licenses (which the Creative Commons licenses are) are pre-emptive grants of permission and all Creative Commons licenses explicitly grant permission to share as long as the other terms of the license are satisfied so, if it isn’t an attempt to add extra terms to the CC license, then it has no effect because you automatically give everyone permission.
However, even if it’s intended to come across that way, a Reasonable Person (in legal terms) would feel uncertain about whether it’s an attempt to add an extra term to the license, and that makes it a violation of Creative Commons trademark policy which only grants you permission to use the Creative Commons name, CC-BY-ND, and the CC logos to describe completely un-modified CC licenses.
(Otherwise, you cast uncertainty on the meaning of seeing a CC badge and dilute the value of their brand, which is exactly the kind of thing trademark law is intended to allow trademark holders to sue people over.)
Here’s the relevant section of the policy:
License Modification:
To prevent confusion and maintain consistency, you are not allowed to use CREATIVE COMMONS, CC, the CC Logo, or any other Creative Commons trademarks with modified versions of any of our legal tools or Commons deeds. Specifically:
- If you make a change to the text of any CC license, you may no longer refer to it as a Creative Commons or CC license, and you must not use any CC trademarks (including the Creative Commons name) or branding in connection with the license. For the avoidance of doubt, this includes translations of CC licenses that have not been made and approved by CC in accordance with the Legal Code Translation Policy.
- If you place any restriction on use of a CC-licensed work that has the effect of limiting or further conditioning the permissions granted to the public under the standard CC license, you must not use any CC trademarks or branding in connection with the license or in any way that suggests the work is available under a CC license. These restrictions often appear in terms of use on websites where CC-licensed content is hosted, or as part of terms for downloading CC-licensed content.
