Doing an Instagram detox is one way to clean up your follower base. Another faster and much simpler way is to avoid accumulating fake followers to begin with.
The majority of people who end up with this problem of fake followers find themselves there as a result of buying followers in bulk from sketchy services online with no regard for what those followers look like or a bad usage of hashtags.
Taking the time to create content relevant to your brand or account theme and selectively engaging with your target audience is the surest way to avoid funneling a mass of fake followers to your account. If you're not sure how you would find the time to do so with your busy schedule there are alternatives outside of buying followers that will help you quickly grow your following with real, active and engaged users. The best alternative by far is the use of automation or an organic growth optimization service like INSTABOOST
Be mindful about the hashtags that you choose to use on your posts, once you choose hashtags like: #like4like, #follow4follow, or general hashtags like: #love #yoga #business and etc will attract random users to your profile.
