"Verified" accounts on Elon Musk's X platform spread nearly three-quarters of the 250 most viral posts containing commonly shared misinformation about the Israel-Hamas war, according to a study released yesterday by NewsGuard, a company that has worked with the European Commission on misinformation initiatives.

After buying Twitter nearly a year ago, Musk overhauled the system for doling out blue checkmarks so that anyone who pays $8 a month can be "verified." Accounts verified as being notable and authentic under the pre-Musk system had their checkmarks removed.
