In all honesty, I would expect at least an organized troll farm to use VPNs ending outside Russia.

Random people in Russia might just act directly, but it's a red flag that's easy to pretty-inexpensively eliminate.

It sounds like at least the Internet Research Agency troll farm used VPNs.

According to court documents, the IRA took several measures to hide its tracks, duping the technology companies who were unaware, or unable, to stop what was filtering through their systems.

The key - and obvious - move was to hide the fact that these posts were coming from Russia. For that, the IRA is said to have used several Virtual Private Networks - VPNs - to route their operations through computers in the US. The operatives allegedly used stolen identities to set up PayPal accounts using real American names.

Yeah, I don't even really have a problem with RT, as long as it's labeled so that people understand that it's the Russian state speaking. But a lot of forums rely more-or-less on the idea that people are more-or-less good faith actors. Very large scale efforts to have people pretend to be someone else and make non-good-faith arguments is something that I think that a lot of our forums can't today handle well.

Arguably, that's a technical problem that needs to be fixed in some way.
