Instagram unban

My friend's device was banned, so I gave him access to one of my accounts. After that, both the account I gave him and my personal account were banned, showing the message that the accounts were connected and didn't follow the Community Guidelines. I appealed, and my personal account was restored, but the account I gave to my friend wasn't. Then, a few days later, my personal account was suspended again. I appealed the same way, but the appeal was rejected. Now it's asking me to submit one final appeal, and another one of my accounts has also been banned.
