I'm torn. This ability has been there since 2.5, and exists as I
understand it to avoid burdensome attribution for Wikis.

But as an advertising attachment exploit it is clearly unacceptable.

There's a difference between contributing work to a massively
collaborative project and using (to take CC's example) an image hosting
service. Can this be made clear in the license?
