With the U.S. government offering tens of millions of dollars to combat Russian "propaganda and disinformation," it's perhaps not surprising that we see "researchers" such as Jonathan Albright of the Tow Center for Digital Journalism at Columbia University making the absurd accusation that the Russians have "basically turned [the Internet] into a sewer."
I've been operating on the Internet since 1995 and I can assure you that the Internet has always been "a sewer" — in that it has been home to crazy conspiracy theories, ugly personal insults, click-bait tabloid "news," and pretty much every vile prejudice you can think of. Whatever some Russians may or may not have done in buying $100,000 in ads on Facebook (compared to its $27 billion in annual revenue) or opening 201 Twitter accounts (out of Twitter's 328 million monthly users), the Russians are not responsible for the sewage coursing through the Internet.
Americans, Europeans, Asians, Africans and pretty much every other segment of the world's population didn't need Russian help to turn the Internet into an informational "sewer." But, of course, fairness and proportionality have no place in today's Russia-gate frenzy.
