Start by making a real account with your real name and add only people you know.
Interact with their posts by liking and commenting
Engage coversations.
Do this for at least 7 days
DO NOT TRY TO JOIN GROUPS THE FIRST MONTH

Then you'll be good to start new accounts
If they reject your join request and report your accounts they might get flaggedDamn, I've already joined some groups (five, to be specific)
