Duplicate items from Rejaw feed

My site is at http://www.danielslifestream.info/ , and today items from my Rejaw feed (http://rejaw.com/people/danielsale/sh...) were duplicated on Soup. What I mean by that is every Rejaw post was suddenly on http://www.danielslifestream.info twice.

I went through and deleted the duplicates, but was wondering if this could happen again. I only have a few posts on Rejaw so far, but this could pose a problem if it happens once there are more to deal with.
