Looking for (onion) links to Deep Web forums, image boards, and social media sites

I am NOT trying to get into anything illegal, nasty (cp or snuff), or too crazy. I just want to post some weird/ranchy fiction anonymously. Deep Web sites tend to have fewer rules about what you can post so I can go a little crazy with my stories. Haha. I just think it would be cool to have some unidentified stuff floating around out there for people to randomly find and laugh at. So I guess I'm looking for like the 4chan, wattpad, and tumblr of the deep web, if they even exist (or if what I said even makes sense).

I'm open to all advice, criticism, comments, or anything that you would like to contribute. Thanks in advanced.
