The link first appeared yesterday for me. I didn't have time to take the survey, though, and this morning it was gone when I logged in. I have one other advertiser that's smaller than Google, but I barely promote them at all. AdSense gets limited impressions on my site, because it's just never performed as well as I thought it should.
