Node hunter on other striders' (public) LifeMap

Interesting conundrum - I’m meeting up with another strider tomorrow for a CityStrides run, and wanted to find an area of our city where we can both make progress. However I noticed that when I use Node Hunter on that strider’s LifeMap, the nodes revealed are the ones I haven’t completed, not theirs.

Should we be able to Node Hunter other folks’ LifeMaps? Is there a reason why this is a bad idea that I’m not considering?
