Most of the people who "demand" five paragraphs a post are the tryhard Advanced guys that think length = quality. 

I mean, I'm perfectly fine with writing several paragraphs a post (I [i]usually[/i] write [i]more[/i] for my own RP), but I'm really not fond of that because it's [i]forcing[/i] you to write that, instead of naturally letting it occur. Like, I believe that, regardless of the standard, people should write as much as they can - otherwise, they're just using filler.
