A report from Twopcharts states that about 44% of the 974 million existing Twitter accounts have never sent a tweet. Twopcharts’s data show that Twitter accounts created in more recent years are less active than the ones started by early adopters from 2006-2011. About 25% of the accounts created in 2008 are still tweeting today whereas only about 10.7% of the accounts created in 2012 are tweeting a little over a year later. Wagemakers says about half of the accounts registered in 2014 have been suspended by Twitter likely because the accounts were spam, compared to 28% in 2012.
