The admins just removed one of my NMU galleries from back in July for a copyright violation. The entire gallery?!
I've said it before and I'll say it again...
If there is an image or images you want removed, JUST ASK ME DIRECTLY, I never say no, I never ask why and it is deleted as soon as I read your request
If you go to the admins for removal, I never know what image(s) were problematic and cannot avoid posting it / them again in future galleries
