Recently, our page received unusual behavior from visitors in India. We are receiving spikes of 200/300 real-time users. It lasts for about 30 minutes, then it stops. It repeats several times per day.
Several people warned me, that someone is trying to use fake traffic to destroy our AdSense, but I would like to know is there any other reason for this behavior?
For now, we are dropping all connections from India, but this should not be permanent solution.
Any ideas about this?
