Holding information about people should be a massive liability. It should actively cost them money to know even a single bit of information about us. They should be scrambling to forget all about us the second the transaction's completed.
This is no child's play. The ads you see all around are designed for you not to click. They just want to inject more metadata to make you more identifiable.
Once I followed one of those fake stories like "look what happen with this pregnant horse" and it was literally 50+ pages of a possibility ai generated story that never ended. If you just moved to the main site the story was hosted the content was completely different and no link to the thing you were reading.
Why would anyone pay an ad for something like that? It needs to have a reason and I don't think it is to talk 52 pages about a horse who was pregnant
