Thank you for your information. I have already marked out fanfictions that I want to report.

We have badfic report threads, where one person will start off and everyone else will jump in with recently found badfic. After the thread winds down, someone might add everything reported to the Unclaimed badfic list. But sometimes not. It's not very official - usually it's just a way for people to commiserate about badfic.

So, report the badfic on this thread, and we'll all jump in. I know I found a couple.

Reporting them is good, I'd check with the board before putting them on the Unclaimed Badfic list, especially as there's a discussion on how we're defining Mary Sues going on further down the page.

To report a badfic, I think you have to add it to this list here: http://ppc.wikia.com/wiki/Unclaimed_Badfic

That's what I got from the FAQ, anyway. I think you can report one immediately, but I'm not entirely sure.
