If you find yourself going through an author's profile - or worse, multiple profiles on different sites - to see how much of their stuff is bad... then you're singling out that author, whether you say you are or not. Stop and step away; we're not really the fanfiction police,and we have no obligation to list every badfic we see.

If, on the other hand, you find that three different fics you peg as bad are by the same person - maybe they're one of the only writers for a specific minor character, or they write lots of crossovers of two specific fandoms - fine. You didn't seek out their stuff specifically - you analysed each story as you found it. And that's okay.

I know at least three, maybe four or five, authors who post nothing but Mary Sue fanfiction on their accounts, and I'm worried that pointing it out will get me yelled at for singling out certain authors.

In my opinion, if anyone else finds an account that they want to do more than one story from, they should limit themselves to two stories from that account. Does that sound good?
