Spam is much less of a problem with closed systems. BTW phone calls aren't a great example. The global telco system has enough players that it's closer to email than Facebook, and telcos are classed as common carriers so there's a limit to how much spam fighting they can do.

I don't really know what to tell you. This stuff does work extremely well, it's unambiguously the case. Google already use a software-only form of RA on the web and have done for years. It cut through spam like a knife through hot butter. They could already detect 10 years ago if a Python script was pretending to be Chrome, or if Chrome was pretending to be Firefox, or if IE was being driven by VBScripts or an IE WebView was embedded into apps that then manipulated the web page externally. No hardware chips or new web standards needed! But, the approach used is/was in the end just a neat hack, and it's guaranteed that spammers will eventually defeat it. Perhaps they already did. I guess there must be a reason why this proposal surfaces now, given the ideas aren't new.

I don't quite follow the logic here. Why wouldn't they be able to save evidence?
