As far as I know in the future spoilers in thread titles will be AGAINST THE RULES.

the reason is quite simple: the most recently bumped thread title will appear on the front of the forums, even if the user is trying to avoid that particular section (Bleach Manga, One Piece, etc...)

So please take others into consideration and do not make thread titles containing spoilers. Feel free to discuss spoilers in those threads where it's allowed, but don't spoil in the thread title. Once this rule comes to pass it will be enforced to the utmost.
