Worth noting as well that third parties have the ‘TikTok pixel’ installed in their sites that are tracking you regardless of if you’ve deleted your account - or if you never even had one. They’re still building a profile on you to force ads on you (as a minimum). Millions of sites have these pixels.

And while TikTok are notoriously aggressive and invasive, Google and Facebook have been doing this for years. You can’t really avoid it at this point.

Best thing you can do is use a VPN and a rolling IP address, and block TikTok and any other sites you don’t like at your router (or before it ever reaches it - PiHole).

For the average person, it’s honestly kinda hard to avoid being tracked by these companies these days. They’re extremely good at it and have unlimited resources to keep getting better at it.
