That doesn't go far enough. There's nothing stopping someone posting in a/the book version of this thread. This is about the TV series, and therefore refrain from posting things in it that haven't been covered yet.
All that should be discussed is things left out of the TV series/how the TV series differs from the books/what has gone on in the TV series.
For instance posting about Dany's age in the books and how it is different in the TV series is fine. Posting that she has dragons before the TV series revealed it would not have been.
