Even if it's not trivial to solve perfectly, there are easy wins to be had.

For example: prevent changing the top-level category of a product. E.g. Shoes should not be allowed to become camera gear.

As always, the internet has already generated a counter example to your rule:

If their goal is to make their product listings useful, they wouldn't include that as a shoe.

It only means that either category is okay, not that it should be allowed to be changed.

But I don't think this restriction would fix all the issues where listing in the same category is swapped.

I like that "Spy Cameras Mall" and Spy Camera Small" work as ways to read the address.

Categories on Amazon are basically meaningless. There are probably more miscategorized products on Amazon than ones in the correct category.

Most users just type into the search field, so they don't end up interacting with categories.
