Technically yes bit the game itself did trended massively during the plot release. Almost everyone knows this right now just like everyone knows toki (another blue archive character that is massively hot and blew up)
The difference is that there's no way to hide a character, unless we started tagging every character yet to appear in the Global version of the game spoilers, which would be pointless when they're getting hundreds of posts and everyone is talking about them, because for many players it's important to know about future playable characters.
On the other hand, A.r.o.n.a getting a new name and joining arona (blue archive) in the shittim chest is a plot spoiler, and specifically for the resolution of that part of the story. If you're a Global player who's not keeping up with the plot as it releases in JP, you have no idea of any of this, though you probably know her original name and what she looks like. You're not even allowed to talk about her in the official discord server, less so specific plot details related to her. I only even know about it because of people spoiling it here on Danbooru, because I actively avoid unreleased plot details.
Changing her name just encourages people to ask about and discuss it, and they're not going to bother adding spoiler tags. I can't support changing tags to be more spoilery than they may already be.
