When I read this article, MR immediately came to mind.

Secret units within the 'Five Eyes" global spying network engage in covert online operations that aim to invade, deceive, and control online communities and individuals through the spread of false information and use of ingenious social-science tactics.

Such teams of highly trained professionals have several main objectives, such as “to inject all sorts of false material onto the internet” and “to use social sciences and other techniques to manipulate online discourse and activism to generate outcomes it considers desirable,” The Intercept’s Glenn Greenwald reported based on intelligence documents leaked by former NSA contractor Edward Snowden.
There have been several regular users who won't reveal where they come from, or anything else about themselves. They are either suspiciously GOOD at Russian for being Westerners who are just beginners, or they don't appear to study Russian at all. They repeat the same info ad infinitum and sometimes seem to be on a script. Incredibly infuriating, to the point that I stopped visiting the site for the time being.

No need to jump to any conclusions or be suspicious towards regular people, but this is definitely a place I would consider using as a pilot site, if I was trying to start a project l like the one mentioned in the article. Honestly, it's a perfect place for trying your wings at this type of stuff. Worth bearing in mind anyway. If I was Admin I think my curiousity would get the better of me and I would take a look at the IP addresses in question and see where they resolve to.
