I can revert these changes. Lots of the revert tools available online are not great for reverting large amounts of changes, and just working with overpass in JOSM is the easiest way to get it done.

I made this query to grab all the buildings you added since the date you stated that you stopped reviewing all objects.

Once the data was loaded, I saved a copy as a .osm so you can use it to add the buildings again when you get approval.

Presently, I'm waiting for JOSM to load the upload dialog, and will have the revert complete today.
