The Washington Post:

Online misinformation about election fraud plunged 73 percent after several social media sites suspended President Trump and key allies last week, research firm Zignal Labs has found, underscoring the power of tech companies to limit the falsehoods poisoning public debate when they act aggressively.

The new research by the San Francisco-based analytics firm reported that conversations about election fraud dropped from 2.5 million mentions to 688,000 mentions across several social media sites in the week after Trump was banned from Twitter.

Imagine if this was done half way through the Trump Presidency.
