I used his service one week and I am mostly happy with it. He does comment follow and like people which in theory follow you back (some of them do)
I got real followers that look at my stuff, watch my instastory, like my posts etc!
What still needs to be done in my case (he or his system followed many people that dont follow me) so they have to be removed.
I dont have the patience to unfollow 2k accounts
The seller promised me to do this for me, I will report back after he did.
I probably have an Instagram project next year for a business, I would certainly consider using him again.
