The problem comes from those that say they don't want to use spoilers and obviously won't whenever they think they can get away with it. It's attitudes like this that have driven some away and made the activity here less then it was. There used to be more regulars and now there are less regulars. (IMHO) I think this is because of some of the people who are being rude and one way to be rude is not to use spoiler codes when appropriate regardless of the thread topic or age of the books.
For example, the new book threads have (in the past) had spoiler codes used even though the thread said (Spoilers!). That was polite and it worked and people could read the threads and chime in as they read the book. Now we have some saying to just post the spoilers because it's allowed. That's rude and that's the sort of attitude that will and has driven some away.
