On: Using your browser URL history to estimate gender

Has anyone considered that this is a massive privacy issue?

Imagine an advertiser detecting which sites you've been to, and serving different ads based on what it finds.

Edit: the author of the script thought of it: http://azarask.in/blog/post/socialhistoryjs/ and it's bugzilla 147777 https://bugzilla.mozilla.org/show_bug.cgi?id=147777

Perhaps I'm in the minority here, but I have far larger privacy concerns than a website being able to gestimate my gender.

Yeah, it's a pretty massive privacy issue, but at least I would hope people wouldn't do it and expect to get away with it.

I would be pretty surprised if people weren't already doing this.

It would be interesting to find out. If any of the big players are doing it, there would be a huge backlash if they got caught for it.

Ad companies already use cookies all over the place to track users, I'm not sure this would be that much bigger of a deal.
