Fanfiction Pet Peeves

Well, I'm sure the title explains itself. What are some things about a RWBY fan fiction that will turn you off very quickly aside from the fairly universal ones like bad grammar, spelling, punctuation, Mary Sues, overly edgy OCs, and formatting?

A big ol' one for me is villains being easily forgiven. Now, if the story was stated to be AU (Cinder is adopted as a child by a heroic character) or a role reversal fic, then ok. But if the heroes just suddenly forgave post-V3 Cinder when she pulls a Heel-Face Turn, then you can consider my ass out.
