Hi pangoSE,
just to understand what you were doing - which are the validation fixes you talk about?
What does "Review by So9q" mean in your "source:lake" tagging?
way/9653990 looks more like a pond than a lake?

implausible landuse tagging; undocumented extrapolation from node to campus (repaired/reverted)

blunt mechanical removal of brand:wikipedia
just an example: what was wrong with United States Post Office ?
As usual, mixed with some minor tracing.

CS was partially reverted,

Hi pangoSE, this gives the impression of a mechanical edit.
Could you tell us about your review methodology, decision criteria, and why you added "source:lake" to each object, instead of the changeset?

Appears mostly repaired meanwhile by local mappers.

ok, this CS appears to correctly substitute outer-way relations with simple polygons.

This CS maliciously deleted a large river segment (because it was not detailed enough?)
