I would imagine that writing a spoiler about a film would take a good deal of text and that anyone with a modicum of intelligence would stop reading it if he did not wish to know more.
Why cut off the leaves when you can grab the problem by the roots? Otherwise it will just regrow.
Also: Why blame other people when somebody can stop being a poophead in the first place? Change starts with yourself, and clockwork had a lot of chances on doing that. This ban is not only because of the spoiler, its the result of a series of no-nos.
btw compared to other forums we got a lot more tolerance here
think of clockwork as a misbehaving friend on a party. It´s nice having him around, but he constantly rubs his butt on other people. At first you chuckle a bit and look away, but he continues so you ask him once or twice to stop it. He doesn´t stop, people are getting annoyed, you confront him and tell him in all seriousness to stop. But he just won´t stop, instead he suddenly pulls down his pants and starts rubbing people with his bare butt. That´s the point where you have to dismiss him from the party, because it would spoil the fun of all the other people. Also, other peoples trousers are getting shitstains from it.
