[OSM-talk] Interesting cases of vandalism?

[Mulone]

(Apologies for cross-posting)

Hi all,
I am an academic researcher and I am studying the issue of vandalism in
OpenStreetMap
(see  http://wiki.openstreetmap.org/wiki/Vandalism
   for a general discussion).
I am very interested in the motivations that lead users to vandalise
OpenStreetMap.
Can you point me to specific instances of vandalism that have an
*identifiable reason*?

Examples might include: 
- People changing borders of countries in conflict zones
- People renaming famous places with their name/interests
- Companies damaging data to prevent competition (such as the alleged
vandalism by Google’s contractors)
- People damaging symbolic places (e.g. deletion of the White House or the
Eiffel Tower)
- People damaging data to bully locals/other users
- People creating imaginary places
- People who are frustrated with the editing tools and start using them to
damage data

Thanks in advance for sharing your experiences!
Mulone

Are you only looking at intentional vandalism? One common thing I've
seen is new users not understanding that they are editing *THE* map.
They just want to make some simplified map for an event they are doing
or something. So they delete all the rivers and some minor roads.

Hi Mulone,

This UN Dispatch article(1) mentions some of the main streets in
Jalalabad, Afghanistan having "joke" names. Note this has since been
fixed by those same mappers.

Hameed who is mentioned in the article also spoke at last years State
of the Map Conference.

I can confirm this, all replies I ever got from people which I asked
about their deletions from the map were saying that they hadn't
understood they were editing the main official database. Usually they
wanted a "clean" printout and therefore deleted some POIs in the way,
or others drew a motorway zigzag over the city center.

Other kind of "vandalism" are mappers who want to "correct" perceived
errors (they prefer different tags, or they have read in the wiki that
a certain tag is "deprecated" and so they delete these tags or change
them to other tags (that are maybe not in broader use)). This is
partly also happening where it wouldn't be necessary from a technical
point of view (different keys), but some mappers think that there
should be _one_ main key describing an object so they remove
"deprecated" tags as duplicates (an example would be highway=bus_stop
vs. public_transport tags).

Yet another kind of "vandalism" (or maybe better spam) is created
intentionally by people in order to promote certain businesses, e.g. a
dance club where tourism=attraction is added.

cheers,
Martin

I remember a case where a contributor was removing shop names (or even shop
POI) because he did not want OSM to become too much shop oriented... but
vandalism is quite unusual.

Ouch, you hit a sore spot there. I'm in the process of adding 35000 stops
for the northern part of Belgium. If I simply add the tags approved over a
year ago, they won't be rendered.
So I'll keep with the highway=bus_stop tag for the time being. Adding both
ways of doing things seems like a waste of space and tagging for the
renderer. Having to retag them in bulk sometime in the far away future,
seems like pollution of the history, though.

So the big question is: when will bus stops tagged with only the newly
accepted system be rendered (preferably on all relevant renderings), so I
can do this operation 'right' all in one go?

I shudder at the tought that removing highway=bus_stop from them would be
considered an act of vandalism. Maybe I should not care about rendering and
simply not add that tag in the first place...

The problem is that people think that a vote on the wiki pages means that the 
far more common tag is wrong. I tag my bus stops with highway=bus_stop (as well 
as operator, ref and shelter/bench information)

The same user that didn't agree with the fact that the new football stadium in 
Nice, France (still in construction) known by local people until recently as 
the "Grand Stade de Nice" make a deal for being sponsored and was officially 
renamed "Allianz Riviera".
A short edit war took place :

+1, in this particular case I also question whether public_transport
will ever become the preferred tag for bus stops, it doesn't offer any
advantages *1 but requires more effort from the mapper for the same
content (you'd need at least 2 tags instead of one, because you have
to add bus=yes, and eventually with the public_transport-scheme you'd
also need an explicit relation for what can be easily accomplished by
software (projecting the bus stop to the stop position on the road).

cheers,
Martin


*1 at least as long as you don't consider it an advantage to have
train stations and bus stops tagged with the same key (personally I
don't).

  It depends on the eventual use - if it's only to create a mark on the 
map indicating the stop position, the old scheme works.  The relation is 
needed for cases where the stop is in the legs of a Y for example - it 
may be physically closer to the left leg, while the actual bus route for 
that stop is on the right leg.

Hi Mulone,
Please list your project on the Research wiki page, and ideally come back
to update it if you write any papers.
