Bot scores for coordinated and random accounts (bot scores vary between 0, organic users, and 5, clear bot activity).

Bot scores are significantly higher in coordinated accounts (above brackets are Mann-Whitney U test p-values) when we measure 100 random accounts, 100 accounts coordinated by hashtag sequences, 100 accounts coordinated by co-repost behavior, and 100 accounts coordinated by activity. All accounts are sampled at random regardless of their activity. (PDF)
