AIUI, I'm myself way below BBS age too, I believe you sign in to a shell program to someone else's *nix box that offers BBS features. The shell that spawns at the remote side is a stripped down ncurses program rather than being /bin/bash. The program allows narrow range of actions such as `ls /var/bbs/threads/`, `cat /var/bbs/threads/$1`, or `cat | sed -e s/^/\n$(whoami),$(date)\twrote:/ >> /var/bbs/threads/$1.txt`. The grumpy neckbeards with accounts on the remote system would have extensive secret sauce for `/usr/bin/expect` that can aggregate changes for each file so they can catch up to the latest flamewars happening there, while it wouldn't be a requirement to be explained how far away you are on spectrum, or something along that. idk. More than happy to be corrected.
