Don't defend advertisers. They are vampires. Don't mournfully look upon them and proclaim, "Even these wretches must eat." Plenty of jobs need doing. Advertising is not, never has been, and never will be one of them.
- noitsnot 7y agoI would like to assume at least Facebook and Google are doing it through their apps and devices but they might not even need the inaudible tones.
- cwkoss 7y agoHas anyone developed a system to embed redundant inaudible signals into an audio signal? Seems like you could support publishers 100x+ more than any other listener by spoofing these, while poisoning the advertiser's dataset.
