That's weird... I wonder if I changed a setting? If I did, I no longer recall doing so.I use Firefox and DuckDuckGo, but I'm seeing the ads on this site. They are not "targeted", they are pretty random.
At least the ads aren't targetted. That's one good thing.
Although... I wonder how fast the AI can figure out your profile and start giving you what you like. Should be a few hours I reckon, maybe a day tops.
