are we really not that identifiable with all of the fingerprinting techniques and what not? the majority of people do not use VPNs to cover their tracks, and most home ISPs don't rotate their IPs that frequently that my tin foil hat suggests that for the non-techie person attempting to foil the IDing, they're IDing them.
Most browser "fingerprinting" methods have a pretty short half-life. The last assessment I read said something like half of the fingerprints were lost within 24 hours. There are some companies that advertise device fingerprinting for moderation/anti-abuse services, but I have yet to see it in any martech stack. I assume they give lots of false positives and don't distinguish between different users/devices on the sam…
That's absolutely not my experience. Maybe if you use some weird research-level fingerprinting technique, but most fingerprints are just regular old boring stuff - screen and browser viewport size, installed plugins and fonts, browser UA and settings, hardware/gpu quirks, etc[1]. And it doesn't have to be 100% reliable, just reliable enough to track your activity to show you some ads.
[1] as a privacy conscious individual I'm fully aware just viewport size is enough to almost uniquely fingerprint me. I use my laptop screen, with sidebery extension, browser tab bar hidden by user css and sway in tabbed mode. My second computer is less unique, I "just" use sway and firefox with the minimal tab size (that for some reason is hidden must be unlocked in the about:config so it's very rarely used).
