Someone posted in r/waymo a video of someone covering all the cameras with tape, which apparently immobilizes the self driving car. I interpreted that as non dangerous to actual people since it keep the car from moving at all.
Anyway, everyone in the comments was a circle jerk saying Waymo should come after the person legally. I suggested that big tech like Google and Uber may do more unethical things than this person putting some tape on a self driving car. Never did I once threaten violence lol.
Check out https://fingerprint.com/. I’m not saying Reddit does this, but there are tons of datapoints they can use to fingerprint you. From what I remember, you can instruct HTML canvas to draw something and you can uniquely identify the person based on micro differences in the drawing. These differences are due to the users unique graphics rendering pipeline (e.g. browsers graphics APIs, operating system, graphics drivers, GPU). Ok so you turn off JavaScript. You can still fingerprint someone using a bunch of CSS tricks.
thats what reddit likely uses.
