Forum:What's with all the spoilers?

My wife and I are going through the show now. We're currently in the 4th season. She has read the books and I have not, so she's enjoyed reading about the differences after each episode, and since I have no plans of reading the books in the immediate future, she reads them to me. Recently though, there have been huge spoilers in the posts about differences between some episodes.
 * SPOILER** I'm specifically referring to a reference to The Hound potentially dying later in the season, and something about Tyrion killing his father.

​I've really enjoyed this website so far, but this is incredibly annoying and I don't have any plans to come back to this page because of it. There should be some kind of spoiler tag or something to keep from having future plot ruined.
