Someone I know well was hired at Twitter more than a decade ago as a senior software engineer. He had experience with natural language processing, and was given a project to identify spam and bot accounts. He worked on this for a while, all the data he needed was made available and he analyzed every account on Twitter. His analysis said one third of all accounts were bots. He presented these results to management, who said the number must not be that high, and discussed what it would mean for their MAUs or whatever metrics if these accounts were removed. None of the identified accounts were deleted. Instead, the project to identify them was canceled, and the engineer quit. More accounts means more money. Follow the money.
