What precedent? You keep claiming it’s related to an EULA, which is wholefully misplaced and have provided no evidence to support this.
There is plenty of precedence that merely a sign or other notice is admissible in court, but again, this has nothing to do with admissibility, it is just so you can’t claim you didn’t know you used a pirated cdkey. Which has precedence has a defence, so they have an already precedented way of dealing with it.
I’m sorry you missed my clear joke in my parent comment, but good to know pointing out your folly is “losing my cool” lmfao.
