A simple whois
(querying a public database) points to Prague (CZ) - and reveals the name & address of one person. Of course that most likely isn’t his personal address, the guy could still live in the USA. And his last name indeed does not sound very czech, could be Russian, but I cannot be sure. Somebody in the fediverse claimed that he’s a Russian asset but I haven’t seen anything that would support that claim, apart from the obvious.
