Up to 48 million Twitter accounts are bots, study says

Someone just liked your tweet. Someone else followed you. Do you know them? No?

They could be among the nearly 48 million bots on Twitter, according to study released last week by the University of Southern California and Indiana University.

The study, which used more than 1,000 features to identify bot accounts on the site across six categories, estimated that between 9 percent and 15 percent of Twitter’s active monthly users are bots. Using Twitter’s most recent figure of 319 million active monthly users, that translates into 28.7 million to 47.9 million bots.
