This is Alexei Navalny, Putin's biggest domestic critic. He's been banned from running against Putin in the upcoming presidential election, and is campaigning for a mass boycott.

Navalny's application to stand against Putin was turned down by Russian election authorities last year.

They cited a past fraud conviction as grounds for disqualification. Navalny and his allies say that the conviction was politically motivated, and used to keep him out of politics.

He continues to campaign against Putin and corruption in Russian public life — and one of his favourite methods is slick, highly-produced social media videos.

They can be seen interacting with staff, and posed outside for conveniently-placed TV news cameras from a pro-Putin channel.

She's appeared on Russian TV talking about her exploits, and has a book out as well, titled "Diary of How I Seduced a Billionaire."

On Rybka's social media pages, she posted photos of herself with Oleg Deripaska, a yacht-owning oligarch.

Here is a better shot of the pair together. Prikhodko is a deputy prime minister in Putin's cabinet.

He also highlights Prikhodko's large house outside Moscow, which he says is much too big for a lifelong civil servant to be able to afford and maintain.

He goes through a painstaking verification process, including flight records, photo analysis and cross-references with Rybka's book to identify the boat.

He says the photos support his claim that the two men were at sea together on the same boat with Rybka — potentially striking deals relating to the running of Russia's government.

Instagram complied, and removed posts from its service at the request of Russia's media regulator.

In a statement to CNBC, a spokesman said: "When governments believe that something on the internet violates their laws, they may contact companies and ask us to restrict access to that content.

"We review such requests carefully in light of local laws and where appropriate, we make it unavailable in the relevant country or territory."

Google, which runs YouTube, has so far not followed suit. They have also declined to comment.

Here's the entirety of video Instagram banned, and YouTube kept up. It's 25 minutes long and in Russian, though it does have English subtitles.
