You need to utilize mobile proxies. Make sure the location of the mobile proxy is the same location the account owner is in. This is critical. If you're in say USA and you're using a UK mobile proxy, you're putting your accounts at risk.So to make a long story short, I have had some success running 4 accounts on 1 iphone using mobile proxies (rotating before switching accounts).
However, with Instagram's new policies and frequent algorithmic updates regarding account integrity, all accounts have been suspended. I still want to run up to 4 accounts per phone, and using a mobile sim is not an option.
Any suggestions of how to run a good setup based on my limitations?
