Greetings,
I am an influencer and have 5000 friends on 2 of my accounts, I can manually sit and invite each of my friends whom I know personally and ask them to like. I have done it before for multiple brands. Hence, I am experienced.
A lot of people/agencies will tell about real likes but in reality these are fake, do not engage and will vanish overtime.
Looking forward to hearing from you.
Kind regards
