iCloud link: could you share a photo via icloud link anonymously?

I want to share a link to a photo via iCloud link. I want to do so anonymously. Is that possible?

if not, what is the impact of changing my iCloud user name to prevent easy identification. Will this be a problem in other locations in iCloud?

Also, how could I request this functionality be added to the system software. It really reduces the power of iCloud link when using with social media if my real name is emblazoned across the image associated with my screen name. It is a bad idea.
