If they are an exact carbon copy of reality and feature a credible source, then it is acceptable... But indeed if reality diverges and no source is cited, this hints at malpractice. If you have any question, your best option is to just ask the author privately.

Well, data in OSM is based on French cadastre ... Google might have the same source ... but both seems to have the very same nodes ... seems odd ...

Did you compare
osm.org/?lat=48.87209&lon=2.7795&zoom=15&layers=B000FTF
and
http://maps.google.com/?ie=UTF8&ll=48.871264,2.779541&spn=0.013323,0.038581&z=15
I don't see the tracks on GM.
Is it removed?

And how do you know about the nodes?
Normally GM shows only pics and no data.
But you can trick them by using routing.

Well there is a node where there is a break in an almost straight line ...
But I think I confused myself with the mapsurfer hack that replacs streetmap in GM with OSM , it seems it now also replaces the data on top of the aerial pictures seamlessly ...it tricked myself ...
I'm feeling Goofy now :)
Case closed : it WAS OSM data :)
