As the quality of a lot of the buildings are really low quality i personally think this should be deleted because it might deter new users from editing.
I keep seeing buildings overlapping roads (this is from yesterday for example: Way History: 1219715458 | OpenStreetMap) and the old data doesn’t seem to have been corrected as promised. I think it should be better to correct old imported data before keep adding new buildings.
In Tunisia alone he mapped an average of 1343 buildings per changeset in the last two months.
The change set give-away, seemingly indiscriminate importing using the MapWithAI JOSM plugin tool, the 438 being the counter the plugin keeps on how many buildings were imported for the change set.
From my own work with this led to eventual abandoning the tool and de-install. Virtually every single building needs correction or position and/or orientation adjustment since it’s based on MS Bing (dated) data. It does not even match BING’s own imagery. Revert.
