Yesterday while browsing the front page of that other site I came across a video of a TikTok user who finds people based on short videos.
Their TikTok page can be viewed here: https://proxitok.privacy.com.de/@the_josemonkey
(and they also have a webpage https://josemonkey.wordpress.com/)
I find it amazing, geeky, fascinating, and creepy that a single person with a computer — not a government organisation — is able to do this.
It all reminds me of that Wired article from 2009 about the man who tried to go off grid and was eventually found by internet sleuths.
TL;DR doxxing has never been easier, don't say or share anything on the web that you wouldn't want printed on the front page of a newspaper.
IIRC the Wired journalist basically won and was baited into taking stupid risks for a payoff.
Video can a tough nut, because it's hard to control every variable outdoors. In text, though, if you learn how, you can stay anonymous. If you're on Lemmy already you might even be a good candidate for it. We don't need to be defeatist yet.
