I found this searching the help info at evilbay, 
seems they believe they have the right to 
regulate what you post on seperate sites. 
Personally, I don't agree whatsoever. It seems as 
if evilbay just doesn't want people recording and 
making it public record details of failed 
transactions and/or contact information of the 
deadbeats (i.e. your own personal blacklist).
