I would advice you to first test the waters, just don't scale that speedly when you're not "sure" the accounts will not get banned.
Test let's say 50 accounts.
Divide them and try different Settings, profile ecc.
Continue and you will find what is better and what is more secure for you.
You have also very active accounts, aged so you have a huge advantage, since your accounts will be likely under ig radar.
Aged accounts without activity are absolutely crap
Aged accounts with activity ---> WIN
If you need ANY help don't hesitate to PM me.
