Geospam or mistake?

Consider it rather stupid to replace a placemark with advertisement, so far no reaction from user:

Ironically, Google doesn’t even index most of OSM changesets. (I had tried to get some changesets with important keywords of a newly named highway into Google, but no luck after 12 months).

If it is spam you could report it here: https://wiki.osm.org/wiki/Spam.
