Twitter has no intention of easing up on its fight against spam users and other factors that jeopardize the “health” of its service, despite the approach costing it three million in ‘lost’ monthly active users.

Investor panic sent Twitter’s stock price down by nearly 20 percent in early trading today following its latest financial report. Twitter posted a record profit of $100 million for Q2, but its monthly user count dropped by one million, with its U.S. number in particular down to 68 million from 69 million in the previous quarter.
