Dear Jack Pham,

you have imported a large city data set which duplicated existing OSM information and had to be removed again.

You then proceeded to import large sets of un-used nodes, e.g. here

http://www.openstreetmap.org/browse/changeset/18400967

Please stop doing any kind of automated imports like that, unless you discussed them in detail on the “imports” mailing list beforehand.

Thank you
