I meant just literally putting the words "Spoiler Warning" or something similar in front of your first post so the anime-only viewers can know that these comments will contain stuff that didn't happen in the anime yet and can avoid it if that's what they want.

For us manga readers the 10.000 Dragons might be old news, but in the anime that number wasn't mentioned yet and the teaser scenes from 176 only showed a dozen or so.
