I'm also mostly afraid of spoilers in the comments section of witcher related articles on gaming sites. I remember a week before Bioshock Infinite released I think IGN published the worlds first review of the game. Someone in the comments section somehow played the game and spoiled the ending. Luckily it sounded so absurd that I didn't attach it any value. Only after finishing the game I realized that the spoiler was actually true.
I fully expect someone to spoil important parts of the story- that's how some people are.
You do know the first rule of article comments is never read the article comments... A rule I break all the time, it is true, but I usually regret it.
Now is probably a good time to remember the first rule though.
TBH also true of "downgrade" threads or the related fashion commentary "threads downgrade" threads too.
