Marking Posts as Read or Unread on Sessionless BBS
In order to avoid user-tracking, the 381chan BBS uses no sessions, no cookies, and is therefore completely stateless. Any state is tracked by the web browser, that is. However, any self-respecting BBS is able to show you whether a topic you are interested in has new posts or not, right?

It’s an anonymous message board system called AnonyBBS. It’s currently deployed on test.381chan.org where early adopters are testing it.
The 381chan, as the name suggest, is yet another chan,...
