Cover Flagging Question

Should a placeholder cover image be flagged?

The first Amazon cover for Grandmaster of Demonic Cultivation: Mo Dao Zu Shi (Novel) Vol. 4 (the blue one with the Seven Seas logo on it) was used before the official cover was revealed: https://www.librarything.com/work/27689012/covers/231106297

I would not.

If you look at the information popup for that cover you will see that about 90 of the 93 people who have entered that book are using the cover you don't like.

I think you are outvoted.

Besides, Amazon is no longer using that cover, so it will probably disappear soon anyway.
