If you've permanently deleted your Instagram account, you can keep it disabled for as long as possible. You can reactivate it at any time by logging in. However, there is one restriction. Instagram currently only allows you to disable your account once per week. The time your Instagram can be disabled depends on the specific Terms of Service agreement, which vary from service to service. For Facebook, you can only disable access temporarily. But for Instagram, you have to disable it entirely for 24 hours.
