Posting spoilers is one of the worst ways to troll; not to mention the amount of players whose enjoyment and anticipation can potentially be utterly ruined.
If you were around the day the previous Harry Potter book was released, you would understand where Aeus was coming from. Every forum was packed with posts giving away the book's ending, in the titles of the posts and hidden behind misleading titles. And, I don't know about you, but I visit the official forums to talk about World of Warcraft. Aeus is off to an enthusiastic start, telling a spoiler-posting player:
Suspended for 9 days, that's when the book comes out. If... [the spoiler occurs] this becomes a permanent.
But while I admire his enthusiasm, with the number of posts on the topic that appeared with the release of the last book, I wonder if it will be practical to keep the forums spoiler-free. However, if you're a fan of the Potter series, I've got to recommend staying away from the forums -- and the general chat channels -- until after you've finished the book.
