Elon Musk said on Monday only verified Twitter accounts would be eligible to vote in polls starting April 15, a move that the social media company’s CEO believes will address advanced AI bot swarms.

Starting April 15th, only verified accounts will be eligible to be in For You recommendations.

The is the only realistic way to address advanced AI bot swarms taking over. It is otherwise a hopeless losing battle.

Voting in polls will require verification for same reason.

Musk also said only verified accounts will be eligible to be in Twitter’s For You recommendations, which displays a stream of tweets from accounts on Twitter.

Twitter did not immediately respond to a Reuters’ request for comment.

Last year, Musk had said Twitter would restrict voting on policy-related polls to paying Twitter Blue subscribers.
