Just an idea, but could spoilers (for TV shows, Sports events etc.) be clearly marked in threads and not posted in the original post?
I ask because while searching through the posts for bargains, I came accross a thread titled 'Who watched Wrestlemania?' with directly under it 'It was a shame ******* won'.
Might be an idea to keep these things where they cant be seen unless you click to look in the thread?
Just a thought.
