Whether it be a troll topic, or even a topic for the cheap "lolz" it is still within the rules to post. Just like anything else around her, an opinion no matter how unbiased, unrealistic or crazy as it may be is allowed to be posted on this board, this is of course, if the topic in question is reasonable to post.
Looking over this topic, it was posted and left here by the poster, there was no reply given by the user (in a trolling manner of any sort), and by the looks of it, nobody in this thread is really upset about it, in fact, it did kick up a small amount of discussion amongst, even the DN regulars, with nobody showing even a hint of anger while discussing.
And I cannot do something that isn't even in my job description to do. The only thing that I suggest would be clicking on the 'Report Inappropriate Content' link in the tab next to the threadmakers post and make your case to them. But looking through this thread, if this was an attempt of trolling it didn't turn out that way, and nobody got hurt, insulted or even really angered by the content of this thread, in fact all of you took this thread like a regular joke thread.
I really don't see any issue with it as of yet, and I really don't think a mod will either, a topic is a topic, and this one didn't get out of hand, but if you would like feel free to report it and get a mods opinion on this one.
