I might be mistaken, but doesn't the "-SA" in "CC-BY-SA" require mentioning the license?
The -sa clause is only relevant for derivative works, not for simple reuse. However, the legal code of both cc-by and cc-by-sa requires that "You may Distribute or Publicly Perform the Work only under the terms of this License. You must include a copy of, or the Uniform Resource Identifier (URI) for, this License with every copy of the Work You Distribute or Publicly Perform." (section 4a, http://creativecommons.org/licenses/by-sa/3.0/legalcode ) IANAL, however, so I'm not sure that this is the relevant part to apply and, in any case, it's up to the author to defend his/her copyright.
True, they ought to link to the license. I think we have to be happy with what we can get, though! As long as they attribute it, they aren't doing too badly. Once we've got people used to writing "Source: Wikipedia" we can start on getting them to do everything by the book.
