RSS Feed display problems

When bringing in an RSS feed, the entries in a category does not have an avatar and as such appears a GUEST POST but because of the lack of a picture the name display appears to run off the left of the category. Two examples of the problem from different fora are below.

Is there a way to link an RSS feed to a guest account with an avatar so that it displays correctly?
