Yes, people can get spammed on a BBS. But, if they post their email on the bulletin board, it's there fault if they get spammed. Not the BBS software. On this listserv: It is public. I could subscribe and get email addresses that way or go to the archives and scan them. Mailman does have an option that removes the sender's address before a post is sent to the list. Perhaps, that should be done. Then, if someone wants to put their email address in their signature they can. In fact, the listserv sender address could be obscured and you could put a link to the private message area of the bbs so that anyone who is a member could contact you privately - without having your email address. So, the bbs, used properly could improve the spam defenses available to the listserv.
