Foreign governments are flooding US social media with bots and fake accounts to shape what Americans think, and it's getting harder to tell real opinion from paid manipulation.

• China, Russia, Iran, and North Korea spend heavily to influence Americans online, using anonymous accounts to fake "social proof."
• The trick is simple: if the first 20 comments attack you, people assume that's what "everybody" thinks, even when none are real humans.
• This isn't new — the KGB spent decades planting ideas in American debate, exploiting free speech as a weakness with little defense against bad ideas.
• What's new is the scale: social media is addictive, anonymous, and now an estimated half of internet traffic is bots.
• Social media companies tolerate the bots because fake accounts inflate their numbers and profits.

Outlook: Expect more scrutiny of bot networks and foreign-funded accounts, with platforms like X positioned to expose how much engagement is fake.
