One of the larger problems in this space is: since we cannot view the inputs that created the problem, we cannot verify that the problem is actually gone (rather than, say, shifted somewhere else less visible but just as harmful).

If this effect was achieved by a word denylist for example: then I expect new slang and code words to pop up to combat the filter.

We should ask for independent review and high standards rather than declaring the problem gone when we individually are no longer impacted by it.
