[Question] How do I run about 100 Insta/Facebook Accounts in a cost efficient way?

Hello my friends,

I have a quick question. What would be the best option to run about 50 - 100 accounts on facebook?

I won't do many actions on the accounts. I just want the accounts to see my own ads and then engage with it regularly.

I would buy a VPS, buy a bot like jarvee and then purchase a residential proxy.

Do you think that this setup works or should I do it in another way?

Greetings
