Sighted: New tracking tool?

This little warning popped up today when I loaded Ace’s site.  It’s new there, although I’ve been getting the same warning from a couple of newspaper sites for the last month or so.  Interesting thing about it is, I’m not filling out any forms; the message just appears as the page loads.

Javascript is another one of those things that I don’t know a lot about, but what I think is going on is that one of his adservers is using some kind of hidden form to do tracking, as a way to get around blocked cookies.  The Ace page presently loads Javascript from two outside sites:[1] Doubleclick and Nielsen.[2]

Since I’m not interested in being tracked, of course I click “Cancel.”  End of problem.

But it’s still annoying.


[1]  There are also several scripts on the Ace page itself, but none that look likely to cause this.

[2]  I’ve had Nielsen’s server HOSTfiled for over a year, because of bad behaviour.

1 What an odd thing!
Is there a link under the pop-up? Are there links under the buttons? Are the links pointing to the same address?

2 No, it's a real Windows dialogue box, not something on the site.  (Here's the post it appeared over in the screenshot.)  The message is coming from the browser, and I usually see it if I'm logging onto a site with a nonencrypted logon page (or when I'm submitting a comment).

There appear to be some JS commands that can pre-fill out and validate form data, and forms can have hidden elements.  I'm guessing that there's also one that can send the form data without user intervention.
