Those are filtered in the data processing pipelines, before the data is exported. Streak-detection algorithms work very well, and they can mask known satellites from the data. It was, in fact, a key requirement of them being allowed to operate. VR is sensitive enough that it can sense the "secret" [1] national security sats, so they filter those early in the pipeline, and only issue alerts for things that are not satellites.

They are not all filtered early nor are they necessarily missing from images. The data can be embargoed until orbits change effectively.
