It may make some privacy-allergy gamers crazy: Blizzard is scanning your browsing history and cookies.

It pays to read the whole thing. Quoting skt from the site:

"Not very bright are you?

The 'Breaking News' displayed on the login page uses an IE control to access the WoW site for the news. As it loads the IE control, it has to run through the standard IE start-up procedure. Which is what it's doing there.. It's not WoW accessing the folder, it's IE."

Oh, and just for additional info....DITCH IE!

Use firefox or something.
