There are investigations linking specific no-name Twitter accounts with less than 30 followers as the source of Musk's and Trump's disinformed beliefs. We are able to trace Trump's conspiracy beliefs of the gold being stolen in Fort Knox to just some random account on Twitter claiming it.

Whoever runs that account has more influence than you. You don't even need Russia or China to plant disinformation on a mass-scale, apparently all it takes is some Twitter Account.
