Today I was watching a few YouTube videos about groundwork with horses. First time I did that. Yes, I was logged in.
Later today, I hopped on Amazon to track one of my packages. And in my suggestions, there were horse grooming kits, halters and the like, even though I had never before looked for things like these on there.
My mail addresses are different on the two places, and so are, of course, my passwords. I am on Linux with Firefox, uBlock etc. So this must be an incredible coincidence, a miracle, mind-reading, or maybe witchcraft?
I wonder what I could tweak to make things like this happen less in future. I am thinking of adding a Pi-hole to my router, yet I am no longer so sure, if it would help?
I can see the devices you use mattering. Where were you watching the videos? Do you have the Amazon app installed on the same device, or on a device with a microphone? My tin-foil hat theory is that the Amazon app is always listening from your phone, based on similar things happening to my wife.
Linux pc. There is no Amazon nor YouTube app for that, that I know of.
