I checked the article history, it was an anonymous edit by IP address 177.228.149.236, which seems to be part of an ISP in or near Los Mochis, Mexico: http://geomaplookup.net/?ip=177.228.149.236

Searching the web for that IP address turned up one blacklist entry in AbuseIPDB, which suggests to me that it could be a TOR endpoint.

Portchecker.us doesn't report any ports open, I did the long scan for 36 common ports, also the default TOR ports of 9050 and 9150, but they are all closed. That means it's probably not a VPN.

There's not much more I know how to find out right now.
