I guess your questions sort of go directly to "what is KYC?" Are we going to trust an Internet user to provide factual information? Or, attempt to verify that Internet user through a more formal process?
With the more formal, .gov sponsored, KYC, I understand providing false documentation is indeed a crime of some sort. But, when signing up for a service that does not undergo formal KYC, then what?
For instance, is your given name "demo"? In using an alternate name with UQUID am I "more guilty" than you because financial transactions will be taking place?
I don't mean to provoke you, I'm just not sure their Terms and Conditions are enforceable...
