We don't give any of our member data to our advertisers, including where you are located. So nobody gets targeted ads. If you are seeing ads that overlap real Instructables content, or replace it, or move out into the middle of the screen, please click on the ad, copy the URL it sends you to, and notify us either here in the forums or by email (info@instructables.com) so we can stop it. We don't allow that kind of thing at all.
