There has been a high number of changesets produced in the last hours from this quest, also on buildings with no obvious spike, like this one which is only slightly curved and does not match the “less than 15 degrees” criteria.

Many old buildings in European city centres are not rectangles anyway. More than 50% of changesets I reviewed are plainly incorrect and damaged buildings that were correctly mapped (with or without the source:geometry:ref tag referred by Joost). One user uploaded about 300 changesets in a single day.

Shall we consider turning off this quest? Or maybe change the code to make sure it only selects buildings with a real spike?
