Unfortunately we have to report something similar is still happening to us from the same source.
Preliminary results show users from Google IP address ranges in India deleting, moving and abusing OSM data including subtle edits like reversing one-way streets.
Two OpenStreetMap accounts have been vandalizing OSM in London, New York and elsewhere from Google’s IP address, the same address in India reported by Mocality.
The most obvious vandalism started around last Thursday last week from these particular users however it may take us some time to do a full analysis. In fact over the last year we have had over 102 thousand hits on OSM using at least 17 accounts from this Google IP.
These actions are somewhat baffling given our past good relationship with Google which has included donations and Summer of Code work. As a community we take the quality of our data extremely seriously and look forward to an explanation from Google and an undertaking to not allow this kind of thing to happen in the future.
Why was the post made? As an open community we respect the privacy of our members. We have to draw a line somewhere between open and closed communications not being available to community members. It was felt on balance that making the minimum facts public was the right thing to do.
What more details can we share? The source IP range: 74.125.63.* and two of the investigated accounts are: http://www.openstreetmap.org/user/kane123 (This user was blocked for a day on Friday… and they continued vandalising on Monday after being made aware of their bad edits Source: http://www.openstreetmap.org/user_blocks/79 ) and http://www.openstreetmap.org/user/sanganabongina
Do you have an example of malicious data? Yes, here: http://www.openstreetmap.org/browse/changeset/10375538 (London), http://www.openstreetmap.org/browse/changeset/10375581 (New York City) where a user from that IP address modified one way streets [reversed and deleted]. Here: http://www.openstreetmap.org/browse/way/145893931/history where a user added a fake Olympic stadium.
Have we spoken to Google? We are talking to Google and sharing all the information we have.
Do we know if this was a coordinated activity? No. We simply know the IP address and the accounts and edit information, we’re not implying a grand conspiracy. The edits were made over many hours over multiple days – nothing that would happen as an accident by a new user.
When and how is vandalism escalated? – Our vandalism policy is here: http://wiki.openstreetmap.org/wiki/Vandalism
Was this all overblown? As a very diverse and large community of over 500,000 user accounts we have a wide set of opinions even amongst the key people running OSM. This is welcomed and every member of our community is free to speak about how they see things.
