just now when I came to Forum Feedback. The popup is from "Question Market". For ME it disappears as fast as it appears.
Most likely the way adds pops up, the URL below wouldn't matter but is there a purpose of allowing a separate popup window asking us to take a survey? This makes several instances where that darn things has happened.
The only information at the top of the forum page otherwise is:
Centered at the very top in lower-case letters is: advertisement
Aligned left: Your opinion matters
Center aligned: Take a quick survey
Right aligned: Yes
