The Artist Biography Field - Should we permit borrowing from other public sources?

[Secret Squirrel]

So our artist pages have a biography field which was provided so that editors could write a short paragraph containing some basic biographical information. At times, editors have posted biographies that were lifted from other sites. We have been able to figure out when this happens and reject the edit.

However, recently there were some "sourced" edits. For example:

http://vgmdb.net/artist/9797

Here, the text is clearly marked as coming from Wikipedia (EN), and the link is provided in the references.

My question is, how would you feel about allowing this kind of sourced information in the bio field? It is clear that we are probably never going to write biographies for the majority of these entries, so opening it up a little might be an option. Obviously we would need to set some stricter guidelines. Also, we need to keep in mind that this goes both ways, and I would want any editor who takes text from en.wikipedia to make sure that it's accurate and properly sourced according to their guidelines, and fix it there if it is not.
