That sounds more like you have guest posting enabled. Otherwise guests wouldn't be able to post.

Smaller boards can stop spam from bots (that is, software, as opposed to people posting spam) by adding custom logic to the registration page. The thing is that this logic may be extremely simple, even trivial, as long as it is unique to the board. Adding a simple "are you a spammer? yes/no" check box can do the trick. Add a bit of javascript to set the correct value and hide the field, and most human users won't even have to answer the question. Generic spam software however won't know what to do with it.

Large boards may be specifically targeted, and if so the above advice won't apply. Also, phpbb cannot incorporate such changes because once they are employed by all boards spam software authors will simply account for them.

As this thread is about preventing spam, it is probably the best place to make this request.
Dangerousprototypes and I, have been developing a mod that blocks off site links, or links to unapproved sites (uses a whitelist), spam words (viagra invest etc), and unicode characters (Russian Chinese etc). The restriction is configurable, so an admin can set how many days/posts the new user has to have before the restrictions are lifted. Typically, this is set low, as it is very effective at stopping spammers, and a minor restriction to legitimate users. Once the restrictions are lifted, the user has the full rights of any other registered user, and can post whatever your board allows. There is an "extreme" version of the mod, which by making a small edit in one of the files, automatically deletes any user who has attempted to post a profile, been warned that they are not allowed to, and tried again.
This mod is still in development, and will need further work doing on language packs and debugging (if any), and will definitely change before (hopefully) final release. It should not be used on a live forum. I have installed a test forum, which is also acting as a honeypot. One problem I have though, is my domain seems to ignored by spammers? Possibly, because I have been using a variant of this mod for some time, and the spammers know they are just wasting their time?
I would be grateful, to anyone who can attract as much spam as possible to it, or even go and test it for themselves.

This forum will be deleted once testing has finished.
This mod is far from perfect, but with some tweaking, could become a very useful tool for forum owners.
If anyone does have a look, and would like to post us some feedback, here is the mod in DEV link:
Spam Hammer

To the moderators:
I hope I haven't overstepped the mark in asking for assistance in this thread. If so, may I apologise sincerely, and delete my post? This thread is about spam prevention though, and this mod is very effective at doing so. So effective in fact, that I have had to make the unusual request to try and attract spam!
The test forum has guest posting enabled, without any form of captcha or question, registration requires no validation at all. I have opened the curtains and shown the spammers the silverware, now we just need them to climb through the window to try and steal it !

Thanks in advance.
Go on ! it's not as steep as it looks.....

Been weeks since I started using Q&A.
Two of three forums has had zero spambots get in, one spammer signed up on the third, but I think it was a human being given the way it happened. Always going to be one that gets in.
Q&A definitely seems to work great with the right sort of question.

I use Q&A but it doesn't help much even though the language I use is not English.

I couldn't agree more!

With Q&A I seem to have completely eliminated spambots; with StopForumSpam most of the few human spammers are stopped as well.

That's because your question is too straight forward for bots. I don't speak a word of Turkish, but I was able to answer the question within a minute. You'd better change it into something else.

What makes you think that spambots only work in English?

If you can answer your question(s) by using Google, then your questions are going to be answered by spambots!

I've setup a tracking code now to see what questions will be answered by the bots, then I'll replace those questions with hard ones.

This whole topic is about tips for dealing with spam. Did you read it (or at least the first page or two and the last 5-6 pages)? Other people have managed to stop spam.
