Twitter announced on Monday that it will start tagging tweets that share misleading information about the covid-19 vaccine, the verge reported. The tags will include links to information from official agencies such as the Centers for Disease Control and Prevention (CDC), tWitter plans to implement a five strike system against repeat offenders, which can lead to account lock-in and permanent closure.

The new tag is similar to Facebook's anti error message banner, or the tag that Twitter started deploying early in the epidemic. They appear as text below misleading tweets with links to information from official sources or twitter rules. Twitter said it applied the tags through a combination of manual and automated censorship systems, starting with English content.

Twitter has specific labeling standards in its covid-19 misleading information policy, but in general, the company targets five types of false or misleading information.

• Misleading information about the characteristics of the virus;

• Misinformation about the efficacy of treatment and preventive measures;

• Misinformation about regulations, restrictions and exemptions related to health consultation.

• False information about virus prevalence and risk of infection or death;

• Misleading affiliation (e.g., claiming to be a doctor or public health official)

Tags are also included in the new hit system for cowid-19 error messages. A harmful, tagged tweet counts as a blow. If twitter identifies misinformation as a particularly dangerous challenge to the covid-19 treatment and invokes a larger conspiracy to connect to viruses (like vaccines, including the idea of microchip tracking people), the company can also delete tweets, which counts as two strikes. Since then, the cumulative blow at the account level will trigger different actions on twitter.

Tagging has always been part of Twitter's larger strategy to combat misinformation during the 2020 election, when politicians, including the former president, tweet inaccurate information. While these tags seem helpful, they don't necessarily prevent people from sharing information. Holding a real penalty, such as a pause, until there are five bad tweets, also means that the error message may only use some text as a warning to spread.

You can see Twitter's various penalties for different numbers of hits below.

• A blow: no account level operation

• Two strikes: 12 hour account locking

• Three strikes: 12 hour account locking

• Four strikes: 7-day account locking

• Five or more strikes: permanent closure
