Fact check: How do I spot fake social media accounts, bots and trolls?

These are some of the figures cited by the German Foreign Ministry in connection with a Russian disinformation campaign that was first detected in 2022, after Russia invaded Ukraine. Known as Doppelgänger, the operation aimed to amplify pro-Russian narratives on social media platforms in countries like Germany. On some days, thousands of the accounts were active, posting more than once per second in a coordinated manner, the ministry said in a 2024 report.

This campaign underscores just how important it is for users to verify the authenticity of social media accounts and identify when content is being published or amplified by bots and trolls. But first, what’s the difference between a bot and a troll? And how can you spot them?

DW Fact check offers tips to help you navigate today's information landscape. Fake accounts are social media profiles that conceal their true identity. Some may pretend to be ordinary users; others can impersonate politicians, institutions or journalists.

Not all fake accounts have malicious intent. Some people may use pseudonyms to protect their identity or for security reasons. Activists or whistleblowers may use fake accounts to investigate sensitive issues.

Bots, short for robots, tirelessly comment on posts, share content, or artificially stoke online debate on marginal or otherwise overlooked topics. Sometimes, they’re entirely innocent, but sometimes they’re intent is harmful. Good bots may automatically share news or weather forecasts, as well as earthquake alerts and satellite images on social media.

Bad bots, in contrast, are designed to imitate genuine human activity to advance a certain agenda. Depending on the algorithm, such computer programs may compose and publish social media posts or comments, follow others, or even send out friendship requests. Bad bots can distort reality by amplifying certain political opinions on social media platforms and drawing artificial attention to certain issues.
