The British Museum's social media accounts have been swamped with criticism for continuing to hold an ancient artefact taken from Rapa Nui, also known as Easter Island.
The deluge of posts, orchestrated by an influencer based in Chile, Mike Milfort, caused the museum to temporarily shut down comments on its Instagram account.
In a post aiming to mobilise his one million followers, Milfort urged followers to demand the museum return a towering moai, or statue, known as Hoa Hakananai'a.
And follow his orders they did.
Since January, the museum's Instagram, Facebook and YouTube accounts have been lashed by online criticism, forcing comments on some posts to be deactivated.
Comments are still limited on certain posts from the museum.
"We welcome debate, but this has to be balanced against the need for safeguarding considerations," a museum spokesperson said.
Hoa Hakananai'a - which translates to "lost or stolen friend" - is a carved basalt statue 2.5 metres in height and estimated to weigh about 4.2 metric tons.
The moai was removed from the island in November 1868 by the crew of the British ship HMS Topaze under the command of Commodore Richard Powell.
On the ship's return to London in 1869, it was presented to Queen Victoria who gave the statue to the British Museum.
In November 2018, the governor of Easter Island, Tarita Alarcon rapu, travelled to the museum and appealed for the statue to be sent back to Rapa Nui as part of a loan agreement.
It is one of the most revered of the island's moai, which are believed to contain the spirits of ancestors.
European museums are facing a raft of claims from governments around the world seeking the return of artworks and artefacts.
The British Museum has long been subject to demands from Greece for the return of the Elgin Marbles, also known as the Parthenon Sculptures.

It maintains the artefacts were removed with the express permission of the Ottoman authorities of the time, and are "part of everyone's shared heritage and transcend cultural boundaries".
