What sort of "future book spoilers" exist? Are you talking the chapters that have already been released? Or are you referring to hints that GRRM has dropped in subsequent interviews or conventions?
I think any hints through unofficial sources (torrent leak, etc) should be put in spoiler tags but anything else should be fair game. Otherwise it is just too darn uncertain as to what should or shouldn't be seen in the clear.
So unofficial leaks - spoiler tags.
Hints/previews from GRRM or his publishers - fair game.
