I think spoilers that are hidden/under the read more thingy are okay, because you don't have to open and read those, but blatant spoilers in comments are a no-go, cause anyone can see and read those.
I think what people don't realize that quoting the posts that have hidden spoilers make the spoilers visible.
Yeah, people have to put the dots and spaces so the reply doesn't show it.
Also, anyone who doesn't want to be spoiled: stay out of the comments. Just don't read them. I find there's ALWAYS something spoily. (Not that I care. The story isn't ruined for me with spoilers, but I know for some it's very troublesome.)
People are doing exactly that, some put it on the first line it's making me crazy!
It's such a shame but I'll have to stop reading the comments. I really enjoyed reading people's thoughts on each chapter, but this week everyone has just been posting spoilers and raws and more people following and commenting :/
GUYS STOP SPOILING IN YOUR COMMENTS WTF.
The least that you can do is put up a warning in your comments of spoilers, there are some of us who patiently wait without looking at raws, don't be such arsholes >.>
