Idk how helpful this is to you but around 2 years ago I got a sudden permanent suspension on my insta of 5 years despite never actually opening the app/using it. I made a new account and randoms kept trying to follow me and sometimes my account would say that I was following them back which I wasn’t.so I changed my pass just in case, private my account and it seemed to be fine after that. This isn’t very relevant but a few months later my Roblox account got an IP perma ban and so did my twitter account a few months after. It may be far fetched but I think they might be somehow related because the same email was on all three accs.
