at the price that it is less tolerant with invalid geometries. A lot
of bad geometries that are currently still drawn some way or another
will be simply dropped. I'm convinced that in the long run this
stricter handling will be good not only for data consumers but also
for mappers, who will see immediately when they made a mistake.

Hi,
It would be a good idea to generate automatically a message to an author or authors of this geometry asking them to fix it, explaining shortly what an error they committed, and informing them that it would be deleted, if they do not fix it. And if there is no reaction after a tolerance period of say one week, then drop it automatically.

Deleting objects from the map without a warning may cause suspicions and misunderstanding. For example, there are areas mapped as boundary=protected_area or landuse=nature_reserve , but local fishermen who want to continue fishing in the area may not like it, or at least have doubts about its shape. By deleting a Nature Reserve from the map the script may inadvertently interfere into a balance situation.

Best regards,
Oleksiy
