You keep saying the word shadow account like it’s some nefarious thing. They are following an existing Instagram account that they already follow, and will get a notification when that existing account starts using a new service.

There is nothing wrong with this.

Using an advantage does not mean it’s anti competitive.

There’s no way an app with 2 billion accounts couldn’t have 1 percent of it’s users take 30 seconds to sign up for a Twitter alternative they’ve been waiting for? Why is this such a conspiracy to people?
