I posted a deal a couple days ago that went under the radar. It was reposted and the repost went to FP. I reported it and the thread was corrected to show me as the OP.
However, if you click to the deal from the FP it still shows the reposter as the OP: http://slickdeals.net/f/8853347-3-pack-oral-b-floss-action-replacement-electric-toothbrush-heads-13-free-shipping
So it's an anomaly in your system when attribution for a FP deal is changed. Something for your programmers to work on on a slow day. Or maybe your system is just slow to update after a revision...
