What a bot network is
Launch library · evergreen read

A bot network is a coordinated group of automated or semi automated accounts designed to amplify particular messages, hashtags, or narratives, often by liking, sharing, or reposting content at a scale and speed no group of genuine individual users could match, which explains why the safeguard is taken seriously.
These networks can create a false impression of grassroots support or opposition to an issue, since a small number of coordinated accounts can generate activity that looks, on the surface, like a broad and organic wave of public opinion, a nuance that shapes public trust considerably, regardless of the specific circumstances involved.
Signs that suggest bot activity include accounts created around the same time, posting patterns that never pause, near identical wording repeated across many accounts, and engagement volumes that seem disproportionate to an account's small number of genuine followers, which is worth remembering in most contexts, a detail that often gets overlooked.
