So I'm trying to run a few different instagram accounts relating to differing businesses. Now I ubderstand that to be safe you want to do around 5 instagram accounts per phone. My question is I already have created 3 accounts from my phone that I used for like a week long and hardly use. Now if I buy more instagram accounts are they safe to use from my phone that might make it over 5 account s even though I only use and post on 3 total? Can I delete the previously instagram accounts? What would be the safest way to accomplish this. Thank you.
