Privacy tab Sites list

I did a Search through older posts, but could not find this.
In IE6 and 7, IE Tools|Internet Options has a Privacy tab. When I click Sites, there is a list of sites already in place. It has entries such as
100hot.com
247media.com
247realmedia.com
2o7.net
7adpower.com
7search.com
8ad.com etc.
I know these sites are in the Registry under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\P3P\History

Where did this list come from?
Various references suggest it comes from SpyWareBlaster, but I can find no reference to populating the Privacy Sites (note--I am not talking about Restricted Sites) by using SWB, including in the SWB Help file.

 

Welshjim:

When you go into Windows Internet Explorer "Per Site Privacy Actions" it says:

How go into SpywareBlaster and click the "Internet Explorer" tab. Scroll down the list until you see "Cookie" in the "Type" column. Do the two lists coincide with one other?

SpywareBlaster adds entries to block cookies as well as entries to block ActiveX processes and also places sites in the restricted zone.

From SpywareBlasters Help facility under "SpywareBlaster Features" > "Protection" > "Internet Explorer Protection":

 

Peeved McAfee User--Thanks for the kind reply.
Based mainly on what you have said, I think I now understand:
1) The Privacy tab Sites list is at least in part created by the last group of Cookie blockers (as opposed to ActiveX blockers) on SWB's Internet Explorer window. (I say in part, since I can add or subtract URL's on the list.)
2) The Restricted Sites list (although it does act to block cookies) does not apply to the Internet Zone. The Privacy Sites list does. So the Privacy Sites list is what is really blocking individual cookies when using the Internet Zone. However, I am not sure whether the Privacy Sites list is still active when I click Privacy Tab|Advanced and specify which cookies (first/third party in general) I want blocked. I suspect the Privacy Sites list is not active if the "Override..." box is checked. Does that mean it is better to not check that box?

Odd that SWB never does use the word Privacy.
