However, following is an update from Jeff, with a little hope:
...They've come to the same conclusion we have - there's no automated way to detect if someone is a spammer. However - the group is working on a mod for the board that would prevent people from posting url's in their messages for the first X posts. They're petitioning the IPB developers to add it to the forum code.

Hello Brenda,
most of the technical (read IT) methods to fight spam are intended to block the spam message itself without caring whether it has been created by a person or a robot. Here is a quick list of action that can be implemented (yes Jeanette, we all know nothing's for free but I think something's worth the cost)
1. CAPTCHA
The simple need to insert a text in a form field copying it from a distorted image can prevent 90% of bots spam. It's well known and adopted by lots of forums (at least here in Italy) among which there are some of the IT experts forum.
2. Enabling of new users
This is an action that must be taken from mods crew to allow a new registered user to post. It's a simple way, to avoid a spammer (not a robot but a person) to register and immediately post obscene messages.
This methods involve a kind of quarantine space where newcomers "prove" (with the simple politeness of the first one or two messages) they're on the forum to talk about drawing art.
I suppose nobody feels under trade if must pass the easiest of the tests: not being sassy
3. Prevent from posting URLs
This can be viewed as an extension of the previous point. That can be intended to work at the same level (parallel enabling) or at a higher level (subsequent enabling). IE: I've been enabled as user and I can now post URLs or I've been enabled as user but cannot post URLs till my Xth message (where X is a number decided by mods crew). Just like Jeff said.
I do not take into consideration the overwhelming method of authorizing all the posts. Its a never ending curse.
In addition to all the methods that can be implemented there are specific antispam filters that web site hosting forums should use. They're the common filters working with a black list of words.
Hope these considerations are useful to the mods and admins crew.
I don't want to simplify the problem, it's true the opposite: I know it's a big problem and difficult to fight. But I think it's well worth.
Thanks for your attention.
