Ok so for a little context, my bf (20M) had a girl be in love with him 4 years ago, but upon finding out the feeling wasn’t mutual and was one sided, she started making fake accounts to reach out to him when he blocked her main account. This went on for 3 years.

Since a year, the nature of the texts he receives has changed. It’s turned to ”you’re being spied”. Now he doesn’t know if it’s the same girl or someone else, but it’s been going on since a year. An Instagram account, newly made, requested to text him just today. That’s all he has as a lead. He just wants to know who’s behind the account. It’s clearly been taking a toll on hi mentally and I’m scared now that there are spying threats and stuff, it could not be just mental.

Just want to know how one can track down the identity of who’s behind a fake Instagram account? Please.
