All of this said, I did some experimenting and found out that yes, copying their link and just simply embedding it could theoretically lead you to getting caught. If they would really take the time to track that down though, that says a lot more about their paranoia than anything else. Tough to be banned without an account and a VPN though.
If you download the image, save it, and reupload it to Imgur, that is a totally different story.
