Instagram term on use


I recently deleted two instagram accounts that I had. After a few days I entered my login details to see if the deletion continues.However, I saw a message which said '' that my account was deleted because it violated the terms of use''. What happen? The final deletion lasts 30 days and those days I did not log in at all to these accounts. Is there any case someone hacked my account and did illegal things on behalf of me ?
Please answer me your experiences in order to find a solution because these accounts had content of me and I didnt know finally if its deleted or hacked .

These accounts were created only with different phone number and not an email .
