Here's a list of the third party sites loading content or setting cookies on ad pages I have found today so far:
- yieldmanager.com -- Right Media
- googlesyndication.com -- Google
- anrdoezrs.net -- Commission Junction. CJ has about a gazillion nonsense domains they use for this stuff; I'm not sure how often they change them around, but it's possible you could be blocking this one one day and the next they've switched to another.
- unicast.com -- Unicast
- indieclick.com -- IndieClick
- adrevolver.com -- AdRevolver
- fatlens.com -- FatLens
- doubleclick.net -- DoubleClick
That's a whopping five eight different sites so far! And that's not even including the Hitbox stuff that has its own LJ subdomain at hbstats.livejournal.com.
So--anyone who is currently using AdBlock and browsing on pages with ads on them, make sure to check frequently for any other third party sites loading in LJ in case I missed them so we can add them to our list.
