If you push it, all the diamagnetism videos people published about reproducing it could be created by some weird and unlikely distribution of ferromagnetism on the sample. Except for the one that nobody knows where it comes from, that could easily be a fabrication.

That leaves the original, that is clearly diamagnetism, but still could be misleading in many ways.

We don't know how many labs are working on replicating this. So we have no idea how unlikely mistakes we should expect to see.
