The European Commission has called for Twitter to step up its efforts after Elon Musk's Twitter lagged behind Alphabet's Google, Meta Platforms, Microsoft and TikTok in the fight against disinformation in the last six months.
The companies have presented progress reports on compliance with the EU EU code of practice on disinformation in the last six months.
The reports included data about how much advertising revenue the companies had averted from disinformation actors, the number or value of political advertisements accepted or rejected and instances of manipulative behaviour detected.
The Digital Services Act, the new online content rules, which allows regulators to fine companies up to 6% of their global turnover for breaches of the code, was strengthened by the Commission last year. Digital services coordinators decide penalties and enforce the act.
Vera Jourova, a Commission Vice-President for Values and Transparency, singled out Twitter for criticism.
She said she was disappointed to see that Twitter's report lags behind others and that they expect a more serious commitment to their obligations stemming from the Code.
The EU executive said that the report lacked data and did not contain information on commitments to empower fact checkers.
EU citizens, researchers and NGOs can access online information about their efforts to combat disinformation through a transparency centre, which was set up by the signatories to the code on Thursday.
