We have a new user and he answered some question (eight, almost the same, answers in one hour) to promote his product ([Example](https://gis.stackexchange.com/questions/397638/best-practice-for-opening-sentinel-2-data-with-python/448186#448186)). He added a disclaimer to the answers after a while. But it is very obvious that he promotes his product.

I've encountered a situation like this in GIS SE before, and I flagged the answers as spam. But they were rejected by the moderators (or reviewers). After a while, those answers ([1](https://gis.stackexchange.com/a/446112/29431), [2](https://gis.stackexchange.com/a/446111/29431)) were deleted by the moderators (or reviewers) as spam.

What should we do if we encounter such a situation (serial promoting a product)? Or what should the moderators (or reviewers) do if they encounter such a situation (serial flagged post as spam)?
