No, that's not how threads or discussions work. If you want to explicitly discuss spoilers start a spoiler thread, no one should be afraid of entering an OT in fear of having the game theyre playing blatantly spoiled.
Here's the problem with that (and it's a problem that's been sorting itself out on the Off-Topic side pretty elegantly, or rather, as elegant as OT can get)
What's the point of having an "official" discussion thread if people can't freely discuss the thing everyone's there to talk about?
The notion of an OT being spoiler free is kinda fundamentally broken. If it's supposed to be
the place for conversation on the story, gameplay, narrative, experience, tips 'n' trix whatever-the-hell, asking people to go there and then immediately telling them that 2/3rds of all possible topics of convo now have to be placed behind black bars (as low-effort as that might be, it's still intended to be constricting/restrictive) or everything is going to get derailed and there are guaranteed to be fights? That really doesn't make much sense.
I know that it's the habit here. It's the tradition maybe, more like, but it's also backwards. It makes no real sense.
What happened on Off-Topic is that review/preview threads would pop up, and since those threads are where everyone is on the same common ground (nobody's played it/watched it, they're all just waiting for reviews to drop)
that is where spoiler free conversation goes. And what's more, the conversations tend to stay spoiler-free
naturally with no constant reminders or pleading, because everyone's more or less on the same level playing field there, with the same intentions within the conversation.
The Official Threads are just naturally considered spoiler threads now, because if you've just seen something, or read something, or experienced something, it makes sense you're gonna want to talk about it openly with other people who have seen it.
That's what a fuckin' official thread is for, right?
That's kinda the problem in a nutshell. Since spoilers as a concern is a relative new thing, and the internet has a memory all of 5 minutes long in terms of social mores, instead of stopping to think about the best way to implement discussion without making things janky for everyone, someone set up the consideration protocols
fucking backward, and the rest of us just kinda... went along with it.
The whole thing is often approached completely backwards, and while yes, being inconsiderate is a dick move, and people could stand to have a lot more consideration when dealing with each other and their differing opinions, suggesting that people who have seen, read, experienced, or played a thing are now the ones that have to
automatically assume the defensive and be extra careful not to talk with others about what they've experienced—
in a thread dedicated to that experience—for the sake of people who basically are just wandering into conversations
they're not even ready to have yet?
Doesn't make any fuckin' sense.
