Instagram create account 4G proxy

hi,

i made right now 7 accounts succesfully no bot, by changing the user agent and cookies delete extension. The problem now is since i'm trying to make my 8 account i get banned right after the registration! i'm using yahoo email instead of mail.ru

P.s. I rotate the 4G proxy so i have every time a new ip when i'm making a new account.
+ the 4G proxy is not abused since i made it my self to be sure...

what more do i need to change? it looks like they still tracking me

i need more idea's

Give sufficient break between accounts creation and login .
