IP address is in Croatia, but the timezone in his profile is GMT -5. That’s US eastern time but more relevantly covers Bogota and Lima. Didn’t we ban a nazi troll from that part of the world recently - could this be them back with a proxy server? Just seems a bit odd to have the IP and timezone disagreeing, and with the IP being an untraceable one…
Having said that, the IP apparently traces to “Ministarstvo financija” and is provided by “Metronet telekomunikacije d.d.” which doesn’t quite sound like a plausible proxy IP.
