[OSM-talk] #AttributionIsNotOptional experiment on OSM France tile servers

[Rory McCann]

Hi Christian,

That's a interesting approach, and interesting to see that it gets results.

If you think it's too rude, or aggressive, you should remember that 
polite words sometimes don't work. If you don't like people shouting at 
you, then it's your fault for ignoring them when they speak calmly. 
Don't complain when this is the only resort that works.

Most of the complaints about missing OSM attribution don't come from 
people using osm.org tile servers. So I'm not sure if doing it on 
OSM.org is very useful. Never the less, there might be benefit in OSM 
taking the next level of action for our attribution. Concerns about 
libelling/defaming someone are legitimate. We don't want to cause much 
more headaches for ourselves.
