Hashtag Hijacking

What it is

Co-opting trending hashtags or creating misleading hashtag campaigns to push unrelated agendas or distort public discourse.

How it works

When a topic trends, its hashtag becomes a high-traffic channel. Hijacking injects unrelated messages into that stream, diluting the original conversation. Alternatively, creating a hashtag that sounds organic but is actually coordinated can manufacture the appearance of a grassroots movement or dominate discourse on a topic.

Real-world examples

  • •Brands inserting product promotions into hashtags about social justice movements.
  • •Disinformation campaigns flooding political hashtags with memes and conspiracy content.
  • •Coordinated campaigns creating hashtags designed to look like organic movements when they are actually astroturfed.

Ethical guidelines

  • ●Co-opting movements for commercial or political purposes disrespects the people involved.
  • ●Hashtag pollution degrades the utility of social media for genuine discourse and organizing.
  • ●Manufactured hashtag campaigns should be disclosed as coordinated efforts.

How to defend against it

  • ►Check who is behind trending hashtags — are the accounts real, diverse, and organic?
  • ►Look for sudden appearance of a hashtag with suspiciously uniform messaging.
  • ►Use advanced search to filter hashtag results and identify coordinated posting patterns.

Account Forensicsminutes

Before taking an online account's word, or taking a crowd of accounts as public opinion, spend a minute on the profile itself: its age, history, posting rhythm, network, and photo, which together show whether you are looking at a person, a persona, or a coordinated operation.

Every playbook entry states how strong its evidence is and when not to use it. Browse the full playbook.
