This reminds me of a recent case where someone readded (not removed) Ukrainian names after their (constant) removals even though said names were added hastily by a different (now banned) user:
That’s why I also consider ezekielf’s suggestion more powerful as this many changes are unlikely to be done by a single user. Of course, editing geometry will easily blow up the amount of changed objects (depending on what’s ultimately counted as an object) Mateusz noted, though I’m sure most beginners do start simple and edit single nodes like shops or stops first, StreetComplete or otherwise (I know I did) and even then, it’s better to start slowly with geometry and don’t edit a huge area.
