When Ayame introduced the game mechanics behind Zombie Survival Online and told her viewers that she had brought in-game items to reality, her loyal fans didn't doubt her.
After all, they had watched Ayame stream for years now and they knew that Ayame wouldn't lie. Furthermore, they noticed how realistic the game graphics were, and even Ayame's player avatar was very similar to her real-life one.
As for Ayame revealing the location of the special event item, Ayame didn't care much since she knew that eventually, other game streamers would also reveal it just so that their popularity would increase.
Since it was inevitable, why not take advantage of it earlier and profit from it?
With that mindset, Ayame didn't hesitate to reveal the location of the special event item space storage bracelet. Even if she met her viewers in the next game, she wasn't worried since her loyal fans were mostly a bunch of simps and they wouldn't mind being killed by her.
