> They are scientists and conservators doing their best, working away in museum backrooms.

Yesterday’s kids are today’s scientists. You what the most popular archeological student prank is? - It’s for a team to bury a modern piece of pottery in another team’s site. So I am not at all surprised if they wanted to play a few practical jokes on the public’s ignorance.

Trolling here means that they followed the tradition of restoring the items - use just the materials they found on the statues. Well the materials found were the base layers - so that’s what you restore. You don’t go adding shading or fades or iridescent paint because it looks cute. They create art that looks like an 8 year old painted it, then laugh at the public “ooh-ing and ah-ing” over the “beautiful” restorations.
