The nice folks who've given us Ghostery gratis are not nice enough to respond to e-mails, sooo...

I've got Ghostery configured like so

Code:
Blocking Options

 Enable bug blocking

Blocking all bugs.

and I know it's doing something, because I no longer see Google Analytics, i.e. utm_ cookies.

On the other hand, though, even though "Blocking all bugs." extends to "DoubleClick," I'm still finding items in Safari> Prefs > Privacy > Details identified as doubleclick.net (Cache) and doubleclick.net (Cookies). (DoubleClick is not unique, but it's the one on which I've focused.)

Can anybody clarify this apparent anomaly?
