Instagram penalizes empty profiles with sudden follower jumps. Publish a few Reels or posts before any large order.
Keep the account public for the whole delivery window and do not change the username while the task is in progress.
In SMMPool pick Followers plus likes or Reels views so engagement rises with the counter.
Start with a modest quantity, verify drop and refill policy in the service description, then scale.
Crypto and card top-ups fund the balance; orders never need Instagram passwords or 2FA codes.
