Wow, I like it when mods can't be impartial and act like big babies like the rest of us.
Anyway, I think a thread title like "The Sixth Hokage" is pretty much a statement of future events. Whether they are speculative or actually have occurred in the manga, such statements will be taken as a spoiler.
I could go ahead and make a thread titled "Naruto beats Sasuke thanks to Jiraiya", then go on to make the thread a speculative topic about why Naruto would beat Sasuke with Rasengan in a fight. The casual forum goer who hasn't read the manga will assume that I've just posted a spoiler, and get very upset, even though the actual thread doesn't discuss future events (well, maybe).
