If you notice the "Recent Comments" section, you can read the first sentence of each post. But sometimes when discussing plots, you can totally spoil someone inadvertently when writing about what happened in the very beginning of the post.
For courtesy, let's try to use the first sentence of every post with a tag like "spoilers ahead" or "SPOILER", etc. like the one shown above. That way, aside from others knowing what you're gonna post is a potential spoiler, anyone looking at the recent comments section can figure out which posts to avoid because they're tagged as posts that contain spoilers.
Thank you for reading! :)
