So, I'm not really who you wanted to hear from because I'm not a veteran or anything but here's my working method:
Virtual machine connected to the internet through Mullvad VPN, set up account, play tut island manually then rest for a few hours. manual cooking quest and a few other things just to pass as legit, I might even do another quest. Rest the account for a few days before I start scripting.
If I never use the same IP during account creation I tend to not get banned.
