@gavinf According to the company 100% . According to Twitter not very accurate. According to Musk on May 13 2022 when he asserted that at least 20% of Twitter accounts are fake and spam accounts it is more accurate than Twitter estimates. According to Forbes that used a similar tool giving a 46.5% fakes on Musk's account last year when Musk had half the followers, it's OK.

@Turanga_Leela @gavinf I would also bet there are sock puppets in the “valid accounts” — fan bois love to do that.
