You're on thin ice:
If you create fanfiction/fanart/etc about real people or ship real people. If the person/people depicted have expressed their discomfort at others creating fanart or fanfic of them, or depicting them in a certain way/style/manner/etc do not do so, since real people can be hurt or bothered by fandoms about them.
If you think I've missed something send me an ask, there's almost always more to add
