We do have spoiler tags, example below in the drop down, but I would just assume the thread would be full of spoilers as it’s for discussion of the episode. I make the discussion posts on the Movies community as well and I usually put (Spoilers) in the title. I just forgot to here. Would that be preferable?

You just have to type 3 colons, a space, “spoiler” and then whatever you want the the “title” of the spoiler to say, e.g. “spoiler” or “nsfw”. Then next line, type the spoiler text, then next line 3 more colons. Like this:

::: spoiler spoiler
a bunch of spoilers
:::

I’ve now typed “spoiler” too many times and it looks weird to me…
