You answered your own question.
There are infinite options of places to post your stories, and it takes several of them combined to put your story in front of as many eyes as posting it here will.
A large chunk of the problems in question could be solved by appointing an active moderator for those forums that don't have one. It's become painfully obvious where you can go and say anything you wish without inconvenience -- let alone consequences.
The problem with that is that umpteen people who never post crawl out of the woodwork to scream "Censorship" every time it's suggested.
The rest are your trade for the audience. Feel free to suggest changes, but just don't expect action. It does happen ( removal of multi-chapter stories from contests, changing the tagline of the LW category ) but such action is rare.
