New York, Jan 19 (IANS): Nearly 24 million out of 284 million Twitter users do not tweet at all, reveals the latest data filed by the micro-blogging site with the US Securities and Exchange Commission (SEC).

This means that nearly 8.5 percent of Twitter users could be robots who never use the service, ValueWalk reported.

The document pointed to mobile applications that the users connect "with no discernible user action involved".

"There are a number of false or spam accounts in existence on our platform. We estimate that false or spam accounts represent less than five percent of our Monthly Active Users (MAUs)," the SEC document read.

"However, this estimate is based on an internal review of a sample of accounts and we apply significant judgement in making this determination," it added.

Twitter's SEC documents show that out of their 284 million users, 24 million are apps or pieces of software connecting to the platform.

"Over 11 percent of all Twitter users connect to the application through third-party software such as Tweetdeck or Hootsuite, potentially Twitter's most active users. Within this 11.5 percent is the 8.5 percent that doesn't do anything," the report noted.
