It is a good advice and should be part of some kind of information to newbies BEFORE they start posting things. When I posted my first thing I had no idea that my text was going to be published without being inspected first by moderators. I thought the spoiler tag was something that LDW put there as part of the preview procedure. This is common procedure in a lot of websites. I'm not critizing LDW, on the contrary, it is nice to be trusted Information when registering would, however, be good and prevent mistakes.
