I just checked the buildings you had removed personally and they were of a completely standard quality that you would expect in the OSM database. It's humourous that you personally use an AI to add buildings for you, one that seems to only recognise sheds as buildings (changeset/162522492), in a completely erratic/sparse pattern that doesn't provide any sort of benefit to data consumers/end users, to be judging others for doing the same. If you're not happy with the quality of data in the OSM database, you're welcome to either fix it, or ignore it. You cannot remove data for reasons such as "low quality".
