Hi bangun and welcome!
You have a good point.
We do recommend that everyone who does not want to be spoiled should stay out of this thread until they see the episode, which would obviously mean you have also seen the preview. But you are correct in saying that the discussion
of that preview should take place in the spoiler thread, and we'll try to do better next week. We got a little excited I think!
We are trying to be careful that the eliminated team
is not revealed anywhere EXCEPT in the episode thread until Sunday 10AM Singapore time= Sat 10PM EST for those of us in the US. But the location of the next stop is something most of us here know and want confirmation of, so I haven't been very vigilant about that.
SO starting next week we will attempt to keep preview/location discussion in the spoiler thread and I will post a reminder to that effect. I unfortunately cannot be here myself every
week (darn work) while the show is airing and we are live blogging, so you may need to give me some time to be absolutely sure any lapses get moved. (I would think by 10PM of the aired day for sure). Hope that helps!
