My wishlist for the best handling of this ...

Have a "whitelist" of sources known to be allowed (bing, landsat, ...) - 
no warnings or alike.

Have a "blacklist" of sources known to be problematic (google, ...). 
Give a clear warning at download "Please note: It is NOT allowed to 
trace data for OSM from xy ..." and a VERY EXPLICIT (red background, 
warning sign, flashing) warning at upload when google or alike was used 
"It is not allowed to trace data for OSM from xy. Please make yourself 
VERY sure that all data you are uploading are in no way derived from xy".

If an unknown source was used, a deliberate message in between the two ...


Reasoning: Using Google or alike to check a GPX trace to be reasonable 
(e.g. the shape of the track corresponds to the aerial imagery) is no 
problem. It shouldn't therefore be banned in principle, but it should be 
made very clear to the user that e.g. tracing from Google is not ok.

P.S: For the message dialog there shouldn't be a "Don't show this 
message again" checkbox :-)
