There is a new feature after you log in account on web-based Instagram. Once you click on your username, you will see detailed info on when it was created. It could be suitable for M/S providers who buy aged accounts.
Not sure if it`s new or not, I saw it few days ago
But it only works for some accounts, not all of them. Some accounts show the account info once you click on the username, others donβt show anything.
