Got an e-mail from adobe

This mail says only that they will remove any assets that violate this specific rule. If you have assets like that, you can delete them by yourself so that they won't appear in the rejected panel. If you take no action, that will also be OK, as Adobe will delete the files. It is meant for contributors who do generative AI by imitating renowned artists, like generate me a Picasso.

Apparently all contributors have received this email. If you have not used any artist names, you have nothing to worry about.

I received it as well, and I have never used the names of artists in my submissions. It's a bit confusing, as Adobe has NEVER allowed AI images to be submitted that use the name's of artists, so maybe only some minor wording has been updated in the updated T&Cs. So it apparently serves only as a friendly reminder.
