Eh, I don't know. I can see why some people can have an issue with spoilers, but I will agree it's a major flaw in the administration system.
For example, I got hit with a notification due to Oracle of Ages (the picture was in the seventh dungeon. But apart from the Long Hook, nothing else was "spoilers".). Now, I'd like to remind you that this isn't an old game, it's on the GBC for Christ's sake. So I can't exactly call that spoilers.
It's like if I got warned because I said that Zelda was Sheik. It's not really a spoiler when it's now common knowledge.
