It's true for some game shows, such as TPiR & DonD, if you don't want the results spoiled, you shouldn't come here. But I think there are two problems here:
1. Syndicated shows like WoF or J! don't appear at the same time in every market. When I lived in Champaign, IL, J! was on at 4:30 PM, which means if I post about it, it could be up by 3 PM Pacific time. Someone in CA may just be surfing the site for the latest news about the 'sports' thread and not realize that someone even *might* have posted about J!, since on the East Coast, there are many markets that J! doesn't air until after 7 PM eastern (4 PM Pacific).
2. Someone may want to see what's going on in the 'Out in Left Field' forum without having to worry about game show spoilers.
My thought--and I'm by no means the moderator or admin here, so do with this as you please, even if that means nothing--would be to add a separate forum under 'Off topic' for non-TPiR game shows. That way, if someone wants to participate in the rest of the site, they can without fear of finding spoilers. Maybe also have a rule about no spoilers before a certain time for the syndies, but that could be debated.
Just my two cents.
