This is precisely what is happening.
Being a narcissist myself, I'm impervious to being emotionally wounded by criticism. After reviewing both the good and the bad, I took /Lit/'s advice and fixed the tense-switching, will soon be shilling my shit all over this place and trying to link up with other authors.
Trouble is, not every author is a bipolar maniac who can shrug off unkind words from bad-faith reviewers. Imagine being some dude who has worked on a book for years, doesn't really have anyone to show it to other than mom and his family. They like it. He wants more opinions and posts it on Reddit, but he's a 4channer, so maybe his book offends a blue hair on /r/writing and he's banned.
So he comes here thinking he could get a more accepting environment, but instead people rip his shit apart. Bro is never escaping his wagie cagie, he'll put the draft back on the shelf and forget about it.
