Twitter cracks down on misinformation over vaccine, begins labelling tweets

Twitter says it has begun labelling tweets that include misleading information about COVID-19 vaccines and using a “strike system” to eventually remove accounts that repeatedly violate its rules.

The company said Monday that it has started using human reviewers to assess whether tweets violate its policy against COVID vaccine misinformation. Eventually, the work will be done by a combination of humans and automation, it said.

Twitter had already banned some COVID-related misinformation in December, including falsehoods about how the virus spreads, whether masks are effective and the risk of infection and death.
