I don’t always know with 100% certainty that a name is fake, but when the spam email contains many grammatical and other errors and is then signed with a name like Tom Brown, then I think it’s fair to say that something is suspicious. Regarding addresses, in this case, this publisher changed its address from that of the incorporation agent it used in Delaware to that of a mail-forwarding service in San Diego. I think the publisher is really based in South Asia and uses American addresses to fool people into thinking it is U.S.-based.
