Last December Instagram reached 300 million monthly active users (MAUs) on the platform, making it bigger than Twitter, which had just 284 million MAUs.
A few days later, however, Instagram deleted millions of spam accounts from its system, which we theorised meant that it was now smaller than Twitter.
Turns out we were right.
GlobalWebIndex polled internet users aged 16 to 64 worldwide and found that Twitter beat Instagram for both active users and account ownership.
When rated by active use, Twitter finished third overall in the survey, behind Facebook and YouTube.
Instagram was fifth, behind Google+. Ouch.
