Fake Instagram account bullying

[wordsareveryunnecessary]

Found out someone made a fake Instagram account of my child. No pictures on it but the name of the school and horrible posts.
I contacted Instagram and they asked for him to send a photo of himself with ID which he won't do. How can I get it taken down?

Why won't he do the one thing they've asked him to do to get it taken down? Would that not be the easy way to sort it out?

It seems very easy to fix.

Instagram have told you how.

If you DS is under 18 surely you have the photo id. If they are over 18 why are you involved.
if they are under 18, hold their own photo and are prepared to comply with Instagram's request you need to ask your self why and consider that your DC may not be innocent.

I filled in the form and received no reply . The only photo ID is a bus pass
