I noticed that if the Autoblog plugin does not find the feed authors name in the blog, it will replace it with a user name from the blog. I would believe this is a violation of copyright law and could pose a problem for some bloggers, especially if a major news source was being used as a feed. They do like credit for their work.
Seems a simple workaround would be to add the name to the admin aliases, and then assign that alias to the post.
If the blog admin wants to change it to look like they wrote it, then they can do so at their own risk and I as a site admin will have taken at least some little step in preventing a copyright violation.
