While the view key of the donation address is public, it seems nobody noticed that a large donation of 1020 XMR was made to the General donation Fund on the 18th of April, which was the 7th anniversary of the Monero chain&project.
The donation is split in several outputs, and we can't even be sure it's from a single entity.
But given the time/block concentration, you can draw your own conclusion.
I can also note that one of the single outputs was of 420 XMR. Which some people might attach funny meanings to.
