Sorry, I'm not positive on where you saw it, so some of this post might be irrelevant. There are 2 sections basically.
If you saw it in someone's Signature/taglineCan you please reference it?
There are currently no spoilers in anyone's tagline/signature that I'm aware of
Mods would've handled that.
If there is something that LOOKS like a spoiler either it's not a spoiler at all or just someone being dumb.
I believe I know what you're talking about, though. I can assure you it is not a spoiler. May look like one, but that has been there since Sasuke 23.
If it wasn't in someones signature:Where did you see the spoiler exactly? Was it in something like this?
If so it's clearly labeled spoilers. So you can't blame the person for that. Besides, it was probably also in a thread titled "Blah blah blah SPOILERS"
So you entered at your own risk.
Also just incase you feel you've spoiled something, there are very few things we know that are 100%.
So whatever you saw might be unreliable.
