It's not that hard to follow/unfollow someone on TikTok; I'm doing this every day! You enter their page, and you can easily see the follow/unfollow button, and then you can press it. I always follow the accounts with popular tiktok songs, these sounds are easy to remember, and you can hear them everywhere! They have become popular due to this platform! Then you can take videos that may go viral yourself on these songs. On a related note, I rarely unfollow someone; I am eager to see everything going on there!
