Table 2. Rupture points in spamming processes and potentially related events. “Date” refers to the rupture points, “Prior” and “After” show the proportion of accounts potentially derived from bot processes for each rupture points, “Days” is the number of days between the rupture point and the most relevant event found in the list within the surrounding days.

Source: Observed and trend values are the actual number of people, seasonal and random values are a proportion of the trend value.
