I hope this is the right place for these matters.

I have found evidence that user Pranas seems to have uploaded lots of

much smells of the Soviet times 20 years ago.  Again, I mapped the new
street again last night, but the incorrect version is still visible in
Mapnik maps:

Most of the imported ways are marked highway=residential, regardless
of whether they actually are residential, or go through industrial
areas, or are the primary roads through the city.

The sad thing is that Pranas seems to have deleted the legitimately
created data that was already there.  So it is not enough just to
scrap all work added by Pranas, but ways deleted by him need to be
