As a long time Reddit user, I've been really disappointed lately with Reddits "battle" against content creators and the little recourse you have if you are marked as a spammer or shadow banned. See the recent /r/indiegaming debacle for example, where a subreddit where mainly indie devs would post about their games now allows very little self promotion ( http://redd.it/2fdwyv ). Some of these rules are Reddit wide so theres nothing they can do but it essentially discourages content creators from being close to their audience on Reddit.
On top of that, if you are banned from a subreddit (even a default one) the moderators can basically choose to ignore you and you are SOL. There's the whole 90/10 rule where if you are posting something from the same source too often, you can be seen as a spammer and banned. It's very easy to break this rule. For example, if you make a few self posts, make tons of comments, post links to 5 different websites, then post 1 link to your website, you are breaking the rule and if a mod sees it you can be banned (comments/self posts don't count towards the 90/10 rule so your 5 posts to 1 self promotion post is breaking the rules). I wish they would just let the upvote/downvote system do its job and weed out content people don't want instead of forcing people to post a bunch of crap they wouldn't normally post just to make their profile look good so they can post about their own projects once in a while.
