Fig 2. The number of bot reverts executed by another bot and the proportion of unique bot-bot pairs that have at least one reciprocated revert for the period 2001–2010.

(A) Generally, the number of bot-bot reverts has been increasing. (B) However, the proportion of reciprocated reverts has not been decreasing (error bars correspond to one standard error). This suggests that disagreement between bots is not becoming less common.
