Disinformation is more prevalent on Twitter (aka X) than on Facebook and other social networks, according to a European Union report.

The report released yesterday is a pilot study conducted as part of the voluntary Code of Practice on Disinformation that was created before Elon Musk bought Twitter, which he renamed to X. Musk pulled his social network firm out of the voluntary disinformation pact in May 2023, but it was still included in the pilot study.
