Twitter Says Error Led to Overstatement of Monetizable Users

Twitter Inc., in the middle of a $44 billion acquisition by Elon Musk, said that an error introduced three years ago resulted in a miscalculation of its average monetizable daily active users metric.

“In March of 2019, we launched a feature that allowed people to link multiple separate accounts together in order to conveniently switch between accounts,” the company said in a statement. “An error was made at that time, such that actions taken via the primary account resulted in all linked accounts being counted as mDAU.”
