If I see ONE MORE OCxCanon Character badfic in chuunin, I'M KILLING EVERYONE. This lates crap has a Mononoke rip off hooking up with Gaara. She's also an Amazon.
Another one, from quite some time ago, has a self-insert getting sucked into the "Naruto World" and hooking up with Kakashi.
THEY WERE BOTH REALLY BAD. Seriously, folks, this isn't Jackoff.net fanfiction.net. You have every right to put it up on chuunin, but when I don't like your story, DON'T BITCH AT ME FOR NOT LIKING IT. That's the risk you take with posting stuff like that up for all the world to see.
Of course, it doesn't help that the mods over there tend to jump on people for "not being nice". *rolls eyes*
I feel you. I avoid Canon Character/OC fics big time. If you don't like the story you have every right to say so just watch how you say it. I usually avoid most fics posted on chuunin anyway. I'm not saying they're all bad, I just don't read them.
If you're giving actual concrit without being rude or condescending then I don't see the problem. Best of luck.
Yeah... I don't read links to chuunin fanfiction. Ever. I stick to recs, strict fanfiction communities, and jumping author favorites.
It really depends on how you word your review. I personally believe that if you don't like it, you can say it in the way of "Your characterization is off because X is like ____," or "This is highly unlikely and rather a repetitive plot." If they post on a public place, they will get criticism either way, that's the woes of real life. Bitching about that is only going to make them seem annoying. If they were a real author they would get destroyed.
If it was a blatant flame like "Your fic sux. Go die." then I see the rationale of telling people to back off. The mods are trying to keep chuunin a civil place without huge wars, wangst like that is usually reserved for forums or fanfiction review rant communities.
But I don't know what's going on since I seem to have a grand time avoiding wangst and badfanfic. *shrugs*
