Hello Yoqtan,

Recently you have added a great number of buildings, all with the comment: “Hachioji buildings”. The (low) quality of this import has been discussed on various channels and also there were questions about the the fact that you did not discuss this import, nor did you create a wiki page for this import.
See the question at your changeset:
osm.org/changeset/118438340

Regarding the import procedure, please read this document:
osm.wiki/Import/Guidelines

A greater problem is that the license for the dataset you used (GSI KIBAN 2500 Dataset), is not compatible with OSM and in fact your whole import should be reverted!
Please contact the DWG to explain your import by mailing us at data@openstreetmap.org, using Ticket#2022031510000175 as your subject.

I block your account to have you read this message, but this block is removed as soon as you have read it and you can continue with your edits.

Best regards,
Marc Zoutendijk
