I went poking around and found some of the affected changesets. Yes,
the changesets had a source=Google tag.

e.g. http://www.openstreetmap.org/changeset/37579334

The problem was pointed out in several of the users' changeset
comments by multiple people.

for copyright or other legal reasons.

There is no active local mailing list, so I'm letting talk@ know
instead. If you are in touch with local mappers, you can forward this to
them. It looks like most of the data that had to be removed was new
data, which will have been removed cleanly without needing any
additional cleanup.

If you have concerns about the source that was used for mapping
something, please contact the Data Working Group at
d...@osmfoundation.org with information, including links to changesets.
It helps if you also start a changeset discussion on one of the
changesets nicely asking the mapper for more information about what they
did.

It is much better to catch this type of problem early, simplifying and
reducing the cleanup work required.
