Hi, please use >! plus a space at the start of any comments that include substantial information about the plot of a work of fiction, especially one that many on LessWrong are likely to read.
Ok will know. However, isn’t it better to mark it for possible spoilers in the post’s title? Just due to the general matter of the discussion.
For now, each comment appears on the frontpage of the site. I think that something like that, an option for each post to be “sensitive” and have comments autospoilered on the frontpage, could make sense.
