this is a very valid consideration. I also quite often encounter people "fixing" situations they don't know by introducing then hard to spot errors because the tags are formally correct but don't fit the situation. Heretical question: Maybe we should exclude tagging all together from the QA tools? Basically this kind of tampering  makes the "cloud-fueled" development of new tags almost impossible, because mappers retag stuff to other tags that are already established even if they don't fit well.

This kind of cleaning worker also are typically very convinced of their work, so discussions with them tend to take a lot of time and energy, often without satisfying outcome (=auto reflection).

I feel we should put even more emphasis on people having been to a place, maybe asking mappers to refrain completely from contributing to places where they haven't been.
