i am aware of an image that i believe violates the terms of the Adobe Stock Photo license. how can i best bring this to Adobe's attention?
Are you the owner of the image? And is the violation being done by Adobe (in the stock site)? If so you can send Adobe a DMCA takedown request. Adobe can't do anything if it is on some other site, or if you are a third party.
But presumably not, as simply an interested third party? I observe that a DMCA notice must include "A certification, under penalty of perjury, that the DMCA notice is accurate, signed ... by the copyright owner or the copyright owner’s legal representative."
Thank you for the additional information, and the link. It is clear that I can't take my issue any further.
