Hmm, now that you bring up captchas that reminds me of how google removed the captchas entirely and changed to the sms verification method. Basically, when creating a google account, you give them your phone number, and an automated system sends you a text message with a unique verification code and then a link to carry on with registration that will expire after a time that I don't remember. When that link is clicked you enter the verification code, and carry on with registration. Actually, I don't think they give you a code, they probably just give you a unique registration link to carry on with registration and confirm that it is you continuing registration. Only problem with that, although most people have a phone or other mobile device, it would be kind of overkill to just assume everyone! has a phone. Second, I'd imagine that spambot programmers has long since worked around this method and have injected fake phone numbers that receive messages into spambots. Additionally, Dark is right about the whole human spammer thing, those guys ought to have phones if they know what's good for them and bad for us, or they fake it themselves. But on the other hand, it does work around the whole captcha thing.

Roro, we're not talking about robotic spammers. We're talking about human spammers now. And my originals suggestion was that it asks you a random question before you post anything, albeit a topic or a reply, etc.

Yeah, I think an SMS activation is good at this way.

Well, why doesn't email activation work here yet? Is it a limitation of the board?

Captchas Don’t Work: How To Trick Spam Bots With a Smarter Honey Pot

Is anyone else tired of being caught in the endless loop of captchas? It can be very hard to read the strange text, especially when it’s full of random letters that look like numbers and vice versa. I really hate it when the letters are so squashed together that you can’t read them. There has to be a better solution!

What is a captcha?

You’ve seen captchas in your internet travels. They are those tests to see if you are a human. Captchas can take the form of a simple math problem or swirly text.

How do you feel about those captcha tests? They make me feel like a site doesn’t trust me. They get between me and my goal, slow me down, and annoy me. I get a feeling that I’m not alone in this.

What is a spam bot?

A spam bot is a piece of software written with the specific purpose of filling out forms with information that benefits the spam bot author. This usually takes the form of comments that contain links which might help their website’s SEO (Search Engine Optimization). A clever author can extract the math problem from your form and calculate an answer. A very clever spam author can also get around image captchas.

So, how do you stop spam bots?

The ultimate way to stop spam bots is to use the akismet plugin. Unfortunately, this service now costs money. I didn’t see any mention on their site of price cuts for non-profits. For a small personal blog or a small non-profit, this is cost prohibitive.

It’s time for a creative programming solution! To stop a spam bot you have to think like a programmer writing a spam bot. The simplest of spam bots see a form and fill in every field on the form. So, what’s the solution?

Well, I was asking more on the theory that it wasn't working, rather than the expectation. I can't remember the sign-up process, but if email activation really is present and isn't working, then we've already got big issues, because human beings can solve any challenge; the actual submission part is completely automated, and all the spammer has to do is click the link in an email. Having used a CR system where only replying is required to approve a message, I can definitely say that it puts up the barrier against robots, but it can't help with intentionally malicious people.

Agreed with Aaron here, I was saw this spam a while ago, but I'm not sure, because this spam makes me confusing with it post's. just this morning, when I look closely, I think it is  not good to me, so I thaught I would report it to the moderators.

Phone verrification? well I'm not running up a massive bill phoning everyone who wants to join this forum, likewise I personally wouldn't want to join any forum that required my phone number (there is some information I just want to keep secret).
