Maximum reels accounts on single IP (home network)

How many reels accounts can post to a single IP daily on one network without reach being limited or shadowbanned all together?

Currently I run 8 accounts posting daily on my home network. 2 accounts per phone. I wait 1 hour between posting to swap to the next account and it has been working excellent.

Wondering how far I can take this before instagram restricts my network for spam. I have another phone ready and can likely get about 12 accounts posting daily, is that too much? Have heard stories of others being restricted for spam at high amounts but I am unaware of the number or range of accounts needed for that to happen.

Thanks in advance.

You're playing with fire the more accounts you run on the same IP but the general rule is 3-4 max
