A user created a thread in this lemmy community remarking that the Tor Browser has a personally identifiable fingerprint under normal settings (the “Standard” and “Safer” modes make you fingerprintable), with several commenters doing the same test and reporting the same. The user who created this post also said that on the privacy guides forum posts about this topic are being deleted.
The poster could try to provide proof. Has at least one of these posts been archived (on archive.is or archive.org)?
Not to be a pedantic nerd but it’s “tenets” and there are absolutely ways to identify people even on tor. Not that extra layers of protection are worthless but it is always safe to assume nothing connected to the internet is 100% secure.
