I forgot to mention that practically every piece of hardware has a recognizable ID. Even the hard drives.
Of course, but being able to remotely request that used to be an issue. The GPU thing is that the browser acceleration that’s in general use can be queried remotely and easily.
I have always used a pay phone for my posts, I call the FR switchboard or the answering service depending on the time of day or night, and they copy down what I say and enter it as a post.
They could trace the pay phone location to within a few blocks, but they’ll never take my freedom (thank you Mel Gibson).
