Ive heard you get some kind of ban for intentionally giving out spoilers in game. I think has to be with the intention of trolling or ruining it for other people. Im not 100 % sure though
I doubt that's true
How can you tell the difference between someone that is genuinely trying to help but doesnt know about the spoilers rule and someone that is trolling but is wearing their best poker face? I played TSW shortly after it was released and there are a lot of missions in there that require you to think and yes even research online the answer to questions. But without thinking people would just blurt out in general chat the answer to some of those puzzle missions which would ruin it for anyone who happened to be watching general chat.
Easy solution (but not the best one) if you dont want your story being spoiled turn off general chat.
