kdawg , for the ebay seller "you.must.have" which was the one you are referring to, i've double checked it, and indeed there were 2 negatives about the 8GB being a hacked 4GB.
However, there were also 8 negatives saying the 8GB was actually a hacked 1GB.
Try going to
www.toolhaus.org and enter in the seller's userid exactly as in ebay. This site allows you to filter all the negative feedbacks to view in a single list.
Alternatively you can view it directly here

It is entirely upto you whether you would want to take a risk and purchase the hacked 8GB player, as it might be 4GB, or more likely 1GB.
