IP and device fingerprinting is the first request the game makes to check if you are eligible, sending them to the server. There's no fixed "token" for it. Each request contacts server, server checks it's database, if it finds your IP and device fingerprint inside their database, it returns the B side. It's all dependent on headers of the request. I tried vpns, changing my emulator device also tried spoofing but none of it seems to work for me. They literally named their nsfw options as B side inside their app as well lmao.
