Banned for faulty logic:
Let's say I'm writing a novel, okay? and I'm about ha;fway through and I decide to use a plot twist. However, later on in writing, the plot twist does something bad for the story, so I edit it to remove said plot twist. At this point, I am not using a plot twist. I did use one, but am not any more. Therefore, anyone banning my novel for not having a plot twist would be correct in saying so, as there is no plot twist in my novel.
Tying back to your post, phantomrage obviously does not have any sort of spoilers in his post. According to my analogy, which is pretty much exactly the same thing that is going on here but in a different context, matpower123 made a completely valid ban statement.
