Are they referring to the mouseover or the actual text link?
I ask because it is a pretty standard rule that you can use a mouseover as long as it's the URL of the paysite, like:
http://links.pimproll.com/?s=stracys...mp2144&j=9&c=1
would have a mouseover of:
http://www.stracystone.com/
but most would not allow the mouseover to read "Click here for Stracy Stone"
