I ended up adding a warning in the description.

If you're new to this game and you're thinking of streaming it, please keep in mind that the game displays your IP address on its window header at some point throughout it, as well as giving you a warning before doing so but it's obviously recommended to play in fullscreen mode at full time.

My apologies for not telling this earlier, as I wanted to keep it a secret. I haven't received any complains so far but I am sorry eitherway.
