From my observation, IG is killing the majority of niche accs (at least for men's fashion). When those accs grow to a specific level, the engagement drops and daily organic followers growth stop. and eventually followers starting to decrease... that's really nightmares. IG donot want us to monetize. Those grew to millions years ago were lucky because they could keep grow based on the big base. But for new niche accounts, it is impossible to be very big anymore. that's my thoughts. welcome to hear experienced IG marketer's comments..
