Its important for me to know if you have purchased followers or likes in the past or currently so I can correctly determine your real engagement rate (not your artificial engagement rate from purchasing followers, likes, views, or comments). The more accurate I am with determining your engagement rate, the better I can research hashtags for your specific account, and the higher results your account will benefit from the provided hashtags.
