I've been struggling for a couple months to block VoiceFive survey popups. They keep showing up on different networks, and now it looks like they've "partnered" with Google (my main ad network) to do their surveys. These popups occur despite the explicit settings I have that forbid popups. VoiceFive is owned by comScore, which is the internet's version of Nielsen Ratings.
To opt out of the VoiceFive survey:
1. Go to
http://voicefive.com/Privacy.aspx
2. Scroll down to the section "Are cookies used by your website or your application?"
3. Click the "Click here" link.
This will set a cookie on your browser opting you out of VoiceFive surveys. You should no longer get popups from them (on that browser) while the cookie is active. If you clear your cookies, they'll come back.
