How do you get 1000 followers quickly on Insta?

I have built a Fortnite creative map and would like to publish it, but I need 1000 subscriptions in social media and I know that Instagram is the fastest way to get followers. Can somebody help me?

You can buy them, but these are usually only bots. If you are looking for real followers who are also interested in your content, it takes time.

It's actually very simple:

you just have to follow some people (but not too many a day otherwise you will be banned for a few days) e.g. Find the official fortnite site and follow the people who have subscribed to fortnite. I did that too and had 1,100 followers in 1-2 weeks
