Reposting my reply to someone else on this topic for visibility:

The Russian scammers are using a ton of proxies and VPNs. Unfortunately, this change will not affect them unless the Russian government completely removes access to the global Internet, and even then, the corruption is so deep that many officials will be selling access to the global Internet to their friends or people with with money.

Russian scammers and social media manipulators are here to stay, likely because they're largely state run initiatives and they'll still have access to the global Internet.

What this does is keep the normal Russians insulated from the rest of the world and unable to coordinate outside of their own country, where everything they do is even more tightly controlled by the government.
