The Sacred Rules for creating fanfiction

Unhinged Regulation for fanfics. Authors who follow these rules will see their fanfics flourish. Over the years reading fanfics on various pages I was able to see the cliches, bad tropes and common stupid decisions that people hate reading in fanfictions. I will post it here and i will give my personal opinion on some "Rules", If you know a new author or a bad one messing up one of the rules, send him the link of this "fic"...maybe he will learn a thing or two... Im not saying this "rules" are always right, depend on the context and the writing skill of the author.
