My wife has about 20,000 followers on Instagram, most of them fake because she was tricked into buying them through "free" Instagram filters apps. It's so interesting watching the activity generated every time she makes a post, the number of push notifications that come through within minutes is incredible. As well, the comments are often absurd on her posts. It's so obvious to a non-Instagram user (ie. me) that there is a tremendous number of bots going around, the fact that Facebook doesn't do something to eradicate the bots indicates to me that they're afraid to reveal the true numbers to their investors and advertisers, otherwise it would drastically affect their income.
