"modified version"
The original game is compiled to IL2CPP. How would that be possible? Isn't it impossible to modify a IL2CPP and the only thing is to look at the code? Are you out of your mind?
Every evidence that's shown in the video can be replicated on people's own computers. Let's include the fact that the IP response is shown ON THE GAME LOGS. And the fact the webhook before it was deleted was named "logger".
You're lucky your audience is full of kids and have no idea what an IP logger is, but I'll tell you collecting personal information including IP addresses, approximate location, and city without consent is ILLEGAL. We have no idea of what you planned with that info. If you were planning an IP blocker, you only would have logged the IP instead. Try my method of just hashing IP addresses for duplicate account checking and IP ban.
