Right, but when you delete an image from imgur you know the image is going away. Years ago Discord wouldn't delete images uploaded as part of a post, they'd just get garbage-collected at some random future time. (And some would leak indefinitely) Thus, people got used to sharing these around and not caring about the original message. Now it's near-instant as the message delete operation sends a Google Cloud delete API immediately. But people still share these around without knowing that. We don't know where those links originated so it's both a disclaimer and a mirror.
