Facebook Group Members Grow 2019

Hello everyone, i'm new and haven't too much knowledge about this topic, actually i wanna add more than 10k members in my group. I wanna do this project using autopilot so which tool i should use and how. Can anyone help me step by step.

Thanks in advance

It's good to hear from you. When you have created a group I do no whether it is opened, group or closed group.

A. Opened group: Opened group in the sense any member of the group a post whatever they like.

B. Closed group: Admin have complete rights whether to approve or disapprove the post which is posted by the group member.

With my personal experience, I request you to go with a closed group and give admin rights to at least 4-5 members who are having a bunch of knowledge about the group(What is the motto of the group) whether to share knowledge or to answer the question.

Important note: If the group is prepared for knowledge sharing and answering questions to the user queries...within a few months of time you can increase the group members more than 10K+

Those days are gone
add members and he added directly to your group
now even if their friend added them they need to accept it to be in
