There are programs that you can get from the App Store or from Google Play. They are going to limit your numbers to 20 per hour. But they can be helpful to get follows and unfollow them from your account.
Make sure to find someone that is similar to you or in a related area then like their pictures and like everyone’s comment. Remember to be real in your comments. Then when you have gotten them as followers, unfollow them. That way it will limit the number of people that you see in your stream.
Don’t do this everyday but every few days. Remember that content is important. Once you have a list of followers remember to always add new quality content that way they will keep following you.
