These suspicious accounts all follow a subset of recommended profiles presented to new Twitter users. In an attempt to estimate the number of accounts created by the automated process described in my previous post, I ran the same analysis tool against a list of 114 Twitter profiles recommended to new Finnish users. After completing the analysis of these 114 accounts, I iterated through all collected lists in order to identify all unique account names across those lists. Across the 114 recommended Twitter profiles, my analysis identified 5631 unique accounts. Here are the (first twenty) age ranges of the most recently created accounts: Age ranges of all suspicious Twitter accounts identified by my script It has been suggested (link in Finnish) that these accounts appeared when a popular game, Growtopia, asked its players to follow their Twitter account after a game outage, and those new accounts started following recommended Twitter profiles (including those of Haavisto and Niinistö).
