I need Facebook group subscribers. Real ones and not ones created with bots. I see that Google proposes a lot of such services, however, I have no experience, who are really good ones and who just sell bots generated subscribers. Do anyone have experience what Facebook group subscribers suppliers are reliable and will give real people who will not unsubscribe next day? P. S. I don't plan to spam this Facebook group too actively. I will post probably one ad per week and some non-advertising articles.
