Accounts getting instantly suspended unpon creation.

Hello,

I've been doing dropshipping via IG reels for a few months and I've just encountered an issue where my new accounts get instantly suspended.
My friend from the Czech Republic offered to help by making a few accounts for me but his IG accounts got instantly suspended as well.
Is there any way to avoid getting suspended? I tried using a Proxy but it doesn't make any difference.

Any help is welcome! Thanks!

If you've already switched IPs and that didn't help, I'd suggest altering the user agent being used to generate the accounts.

I'm not familiar with "user agents", is there a simple way to change it?
Google wasn't really helpful..
EDIT: Just found out how to do it but again the new account got banned. I did it manually in the chrome brower. Am I doing something wrong?
