Is the importing of user data automated? If so, it seems to be stuck at a point 4 days ago

Guess I'll find out pretty quickly if HTML is supported in these diary entries...

Can anybody comment on the legality of using Google Maps to get approximate lat/lon points, formatting those points into a GPX file, and uploading to OSM? I just want to know if I can be open about it, or if I have to be sneaky. It's inaccurate enough that nobody could tell, by looking at the data, how it was sourced... but if this is really a Bad Idea, I'll just have to come up with another method, or save up for a GPS unit.
