How many accounts per IP?

Hello BHW I have made some facebook accounts in the past and have recently come upon a super aged account from 2012 that I have. I recently have scraped some IG pics and put it on the profile, am going to phone verify it and start gathering followers. I am just wondering how many facebook accounts I can use per IP. Right now I have only 1 profile on my real IP but am considering getting proxies. I have also heard that people get banned due to using proxies so I am not sure what to do.

1 account per ip only, if you use more than 1 it will give you a goverment id verification sometime, so 1 account per proxy is the safest, if you're running hundreds of accs. the proxy must be dedicated too because semi dedicated can give you instant ban.

Imagine a big corporation that has a firewall and 1500 users going out through that firewall.

Facebook will see only one IP for all 1500 people. Same happens with a lot of access providers with millions of users in some countries and some companies.

The IP is not the most important factor. Think about the other variables involved
