What I like about message boards is you can get out of them what you want to. There's an active message board for everything. I've been using message boards for a long time, specifically anonymous ones because I don't like making accounts and having a post history (that's why I'm so reluctant to post on my website.) I thought I would share something I made for myself, which is my list of worthwhile anonymous message boards I check regularly. Worthwhile means I believe they have some potential to hold good content, along with being active enought to expect new posts every few weeks. There are many lists of anonymous message boards, but they aren't curated like this one is. Most have a technology or programming board, and if you are looking for a message board that isn't technology-oriented, then it's probably just a regular website and not something like a hidden service (explained below.)
The list contains .onion as well as gopher and terminal-based message boards. You might be confused how to view some of these message boards For normal website message boards I personally either use xlinks or qutebrowser depending if they use images, but I'm an insufferable hippie so you can just use firefox or something. If you use chrome: don't. For .onion websites i use xlinks and Tor Browser also depending on if they are an imageboard or not. xlinks is tech hippie garbage, if you don't know what it is just download Tor Browser. Do not use Brave's Tor feature. For gophersite message boards I use lynx, and I recommend checking here for something familiar. Notably, firefox and chrome have extensions that allow for the viewing of gophersites. But what did I say about using chrome? For a terminal-based message board you ssh into, use a terminal emulator like Windows Terminal or puTTY. If you use macOS, just use the terminal app already installed on your computer. If you use linux like I do, you know what to do.
It makes me cringe a little bit hyperlinking wikipedia for so many things, but I'm trying to keep stuff on this website accessible to anybody.
Here is the list. I'll be actively maintaining it, adding new sites as I find them and removing dead ones as time goes. I also want to note that message boards that require some sort of account but let you still post anonymously, like the sdf.org and tilde.town BBS's are not listed.
That's all for now. Happy valentine's day.
