I'm sorry to be a day late replying to you. By the time I saw your reply yesterday, I had already done my 25 videos for the day. Here are two pages where, unfortunately, the same bra ad popped up today. Normally, I would see as many as six different ads, some worse than others, in one day. These page links don't really prove anything, because the ads are random. They pop up in different videos on different days. If you go to these pages, you aren't necessarily going to see the same ad I just saw. I find it hard to believe that AARP's advertising department is not well aware that these ads exist. This is a screenshot from the only bra ad I saw today, and this ad is certainly not the most suggestive I have seen on here. (In its entirety, the video is worse than just one clip.)
