Hi thank you for the information, that is very insightful.
I want to point out what the user above you said. He says that an @handle can carry over the low trust score, but it’s on a case by case basis for Instagram.
I do believe he is correct, because I had an account get flagged as spam with a low trust score, so I just made a new account, but I kept the @handle. It turns out on my new account, people cannot find it when they search for the @handle on Instagram. So, it appears that the handle itself has carried over with the low trust score.
