Also, I have seen on many sites google maps with an "API Key Required"
watermark.  This really seems like a similar situation.

So perhaps Christian could put a fairly loud attribution watermark over
the tiles, so it's basically functional but attributed.

Overall, I think this is a great experiment, and the combination of
failure to attribute and use of donated tile services is particularly
worthy of addressing.
