To get instant pushback from other mappers is fairly unusual; I would say you had bad luck (or live in Lithuania). In a lot of the world, edits correct or incorrect can take months or years to be noticed by another mapper.

But with regard to bodies of water, there are systems that monitor OSM and warn if someone has tried to "move them to the right place". These details were often added to OSM from professionally surveyed maps, so they are in the right place. However, ordinary people's consumer GPS is typically a few meters off, and they end up moving things to the inaccurate coordinates on their screens.

Is Lithuania known for particularly engaged OSM mappers? (wondering what reference I'm not catching)

For long years it was dominated by one mapper who considered the country his personal project and insisted on an idiosyncratic tagging scheme. He became infamous for instantly reverting edits even by savvy mappers. Intervention by OSM's conflict-resolution body has reduced that somewhat, but that country remains a special case.

		The utterly insane way the Danish community forbids linking addresses to POIs (shops, restaurants, you name it) comes to mind. They've built a system where they import all addresses, but they never managed to make it work in combination with user contributed data, so every address gets deleted unless imported by their official import tool. So a restaurant can never get associated with its address in Denmark on OpenStreetMap. Meanwhile, the Dutch community also imports all official addresses, but there the tool simply allows for these to be used with other OpenStreetMap tags. It makes you wonder about the Danish approach.

The times I have done something in Germany the pushback has been swift and not very friendly so I stopped. I guess it's a localised problem, haven't had any problems in Sweden so far.
