Deleted image

Had a post of mine deleted without any prior notification. Mind letting me know why it was taken down?  
It was a collage of around 25 different artist’s work in one.

Collage contained an image from an artist that recently went DNP. Shit happens.

Mine telling me which artist?  
And can I retroactively change the contents of the picture so as to not contain said artist, assuming it’s still archived somewhere.
