Researchers at Indiana University have developed an app called Bot or Not, which is designed to identify 'robot controlled' accounts on Twitter.
According to PC World, there are the bots that mislead, exploit, and manipulate online conversations with rumors, spam, misinformation and slander.
Researchers revealed that there are companies that sell Twitter followers, which are not always real.
The app lets users type in any Twitter handle and then the app's algorithm looks at over 1000 features to determine how likely it is to be a ' bot' on a scale of 1 to 100.
At present the app is in beta version, and researchers are working to refine it.
