I've looked into setting up new users so that their initial posts have to be authorised, but the administrator of the board says, because emails for these aren't generated, it's taking up too much of his time to keep his eye on the board for any being posted (he only pops on every day or say - the board isn't *that* busy).
There's no real good way to stop human spammers. Blocking initial posts can help, but a dedicated spammer will post one innocuous post, get it approved, and then spam you like crazy.
You can try banning IP addresses, but if those are shared, you might be banning other people. That said, I've banned IP ranges from my entire Web site; they're in China and have submitted false URLs against my site, so I've blocked them because I really don't care if Chinese users can see my site. Blocking IP ranges in known spam countries (China, Russia, India, Pakistan, etc.) might help if you don't cater to users in those countries.
I've also blocked all *.cn, *.ua and *.ru E-mail addresses and have an extensive list of disallowed names (anything with "viagra", for example).
