The Reuters article directly reported only two domains in writing:
But by looking at the URLs of the screenshots they provided from other websites we can easily uncover all others that had screenshots, except for the Johnny Carson one, which is just generically named. E.g. the image for the Chinese one is www.reuters.com/investigates/special-report/assets/usa-spies-iran/screencap-activegaminginfo.com.jpg?v=192516290922 which leads us to domain activegaminginfo.com.
Also none of those extra ones have any Google hits except for huge domain dumps such has Expired domain trackers, so maybe this counts as little bit of novel public research.
The full list of domains from screenshots is:
This brings up to 8 known domain names with Wayback Machine archives, plus the yet unidentified Johnny Carlson one, see also: Section "Searching for Carson", which is also almost certainly is on Wayback Machine somewhere given that they have a screenshot of it.
