As a non-native English speaker, I'm not very familiar with the license terms of Shutterstock. IMHO I should not use watermarked images and instead buy a license.
If posted on SE sites, the image becomes part of the question or answer and thus is licensed as CC-BY-SA, right? So even I buy a license, I should not use it in a CC-BY-SA post.
Then, should we delete e.g. this Lifehacks answer, which uses a watermarked Shutterstock image?
What is the appropriate action for me? Flag a moderator? Actually, I don't want to create yet another SE account just to flag it.
