Given their inability to accurately describe what is infringing in DMCA notices, why would you possibly think they could produce an accurate 'master list'?
Worse the 'master list' would need to somehow handle 15 people having permission to post something and nobody else having permission. What if I change my domain name? How does it now become 'approved' when it no longer matches the 'master list'?
So how do I have completely anonymous phone and email meta-data. Because I CAN send an envelope without any return address on it. Drop it in a random P.O Box and you simply don't have any way to tie it to me without opening it.
Doesn't work for electronic communications unless you're saying we're allowed to encrypt everything...which apparently allows the NSA to store your data indefinitely.
Oh and caller-id spoofing is technically illegal isn't it? According to the blank envelope concept though, it should be completely legal, no?
