A Twitter executive has said that a new "community-driven" misinformation moderation pilot called Birdwatch could get "messy."

The social network announced on Monday the scheme will be taking place in the U.S. using similar techniques that have proven to be effective on Wikipedia, giving users the ability to flag posts and submit notes that provide "informative context" to potential false claims. Wikipedia lets anyone on the internet edit its content, but is ruled over by a wider community.
