With respect, I am 100% sure that Google does this (no insider knowledge here - just conjecture on my part). I am completely sure that Google - a company that lives and dies by data - keeps logs. But there is zero value sharing this with "customers". If you shared this and it said "Algorithm/Employee #12345678 linked this account with previously banned account" where does that get you? It doesn't get you any further - all it gets you is another thing to argue about, but they've already made their decision and you agreed to their TOS about how they can cancel your account at any time, so you've gained nothing really: Google still don't want to do business with you, sorry.
