I have a fan account on Instagram for 5 Seconds Of Summer, feel free to follow me. My username is vanilla.ashton
There are a few ways to get thousands of followers and here are a few that I used
1. Follow other accounts. The more you follow, the more followers you'll get.
2. SFS, ask people to share you and then you share them.
3. Comment on famous peoples photos to get people to notice you.
