Don't do that, please!
First, it's against Openstreetmap's licensing terms to use their data without attribution.
Second, I think it's rather uncreative. That's not what Opengeofiction is about.
If you import small amounts of data from OSM temporarily to use them as an orientation for object sizes, that's probably OK. But if I see imported data from OSM to be used permanently then I'afraid that I have to delete them.
