I want to poison as much of my online data as I can, and I know that companies can get it anyway if I delete it, but if I were to spam sheer volume, it would cost more than it’s worth to try and sort it.

Dad uses windows and the main device I use is his laptop, and I understand that Microsoft scrapes everything they can. He’s going to reset his laptop soon, so all the junk is erased, but would it be possible to temporarily poison most data on there (from ms perspective) until it’s reset?

Would it be possible to do that on other things too, say corporate owned software, social media, etc?
