The Short Version
This claim is misleading on multiple levels. First, Elon Musk himself publicly disputed the "<5%" bot figure during the Twitter acquisition, claiming bots exceeded 20% — so attributing this figure to him as "accurate" is paradoxical. Second, the "<5%" estimate was never independently verified; the most direct supporting evidence comes from litigation testimony by Musk's own legal defense. Third, while many studies suggesting far higher bot rates measure different metrics than mDAU, the sheer scale of bot activity on X (800 million accounts suspended for spam in 2024 alone) raises serious doubts about the figure's practical accuracy.
