[OSM-talk] Still need for spam protection and if yes, what about OSM-based CATPCHA?

[Peter Wendorff]

Hi Stefan.
OSM is not a graphics oriented project, it's a data oriented project.
The graphics use case is the most common and therefore the first one
widely used, but navigation is not graphics based, statistics are not
graphics based, address search is not graphics based, and even maps
exist aside of graphics (e.g. haptical ones, acoustical ones).

regards
Peter
