The global effort on COVID-19 vaccine is underway. And Twitter wants to ramp up its efforts to stop the spread of misinformation against it. The social network will add new labels for tweets with misleading materials. It also comes with rules to punish repeat offenders by suspending or banning permanently.

The strike system has intensifying punishments for rule violators: One strike: no account-level actionTwo strikes: 12-hour account lockThree strikes: 12-hour account lockFour strikes: 7-day account lockFive or more strikes: permanent suspension Users have many chances to reconsider their behavior. They can also appeal their strikes and suspensions. The approach may seem harsh in some areas. But Twitter plays a key role to connect...
