Sick and tired of your inbox getting flooded with spam coming from the "Contact Us" system on your xenforo install(s)? You've tried everything and still it persists? You even shut off the "Contact Us" form to guest visitors? You need the [OzzModz] Contact Us Spaminator.

This addon is a weapon in fighting spam bot submissions to the "contact us" form at your forum.

How it works

The [OzzModz] Contact Us Spaminator injects false fields and checkboxes into the contact us form which browsers don't render so humans never see. But the bots fill out the fields and check the boxes - identifying themselves as bots and falling into the Spaminator trap. The Spaminator then logs all the information and sends the bots to the home page, and gives them the message successful prompt, completely stopping automated contact us form spam while ensuring no flags are raised in the bot program. The programs "think" tthey sent the spam successfully, but no email is sent!.

The [OzzModz] Contact Us Spaminator works with and regardless of other anti-spam measures but also makes them all obsolete, proving the worthlessness of captchas, puzzles, questions, timers and the like, by STILL catching bots while all of this annoying standard anti-spam miscellany is still active. And it won't interfere with any custom fields you have on your contact us form.

[OzzModz] Contact Us Spaminator is completely independent and doesn't rely on any third-party databases, lists, or IP blocking. It presents more opportunities for the bot to slip and prove it is a bot, for better defense from automated spam. So we can combine multiple checks as opposed to only one CAPTCHA/ReCaptcha and/or a question or two per form. This gives huge advantage to [OzzModz] Contact Us Spaminator.

Since programs like XRumer have defeated CAPTCHA/ReCaptcha, email verification, Q&A, timers and many other spam blocking techniques, [OzzModz] Contact Us Spaminator brings a whole new set of checks the bots will fail.

Advantages Of [OzzModz] Contact Us Spaminator

There are many advantages of [OzzModz] Contact Us] Spaminator over CAPTCHA/ReCaptcha, email verification, Q & A etc:

  • [OzzModz] Contact Us Spaminator does not in any way interfere with legitimate human users. It requires nothing from the submitter. No puzzles, captchas, questions, timers or the like. Legitimate humans will never see it or even know it is there. We shouldn't have to prove we are human, to submit a contact us form on a forum.
  • There is no limitation on the number or types of checks [OzzModz] Contact Us Spaminator can implement on forms, so it can get progressively stronger as needed.
  • If the bot programs try to adjust, [OzzModz] Contact Us Spaminator will be updated with new recipes to defeat them.
  • [OzzModz] Contact Us Spaminator needs very little configuration.
  • Everything is logged and viewable by permissions, so there is assurance that no legitimate humans are being blocked and you can gather much information about the failed logins, including IP address, what email addresses were used, and so on.


Four Spam Prevention Options I Avoid


A captcha is an image that renders text in an not-so-easy-to-read way, also known as challenge text. By requiring users to type the challenge text into a text field, it supposedly verifies some form of human interaction and intelligence. So if what the user enters matches the challenge text, the user is believed to have successfully completed the challenge and their form submission is allowed to proceed.

But this has been defeated by XRumer and other automated spam programs.

Another option is implementing one or more question and answer fields. For example, a registration form may include questions like: What color is an orange? Humans can easily answer the questions, whereas spam bots supposedly won’t be "smart" enough. Once submitted, the answer to the question is checked, if it’s correct the form is assumed to be submitted by a human and can be handled accordingly.

But this has also been defeated by XRumer and other automated spam programs.

Banning IP addresses
Banning IP addresses isn't reliable because those can be spoofed or reassigned and you might actually end up blocking legitimate users; spammers tend to use dynamic IPs anyway - including common mobile provider ones!

Third-party solutions which use ever-growing databases of known spammers to compare against.
I don’t want to rely on some third-party solution because the fewer dependencies I have on my site the better I’m going to feel about it - what happens when the third party is down? Plus this also has the potential of blocking wanted users as well as unwanted ones and often does. Some people will argue that the added complexity is a necessary evil, but I just can’t seem to bring myself to agree.

All Degrade The Visitor Experience
While all four options are common and can help prevent some automated spam, I don’t recommend them because not only do they often fail - they interfere with and degrade the user registration experience. Often times these challenges are frustrating to deal with and prompt users to leave. Why is it on us, to prove we are human? A good example of that is captchas which output text that’s too hard for humans to read, or when the Recaptcha checkbox fails, now we must complete a picture puzzle? No thanks.

For that reason I always recommend implementing the least obtrusive options available.

Frequently Asked Questions.

Why do I need such a thing?

A: To screw spambots.

Q: Does this do anything about human spammers?

A: No, this works only on automated contact us form submissions - but the actual human spammer has become more and more rare and is easily dealt with in other ways - most of them which do exist, still use automated programs to use the contact us form anyway.

Q: Has this been tested at all?

A: Yes, extensively. The [OzzModz] Contact Us Spaminator has logged over 10 thousand blocked bot login attempts in exhaustive testing for five months on several forums - without allowing ANY successful automated contact us form submissions or ever interfering with any legitimate human.

Q: Does this alert any possible real people that their contact us form has been rejected?

A: No, there are no "gotchas" in the Spaminator, because no legitimate humans will ever see it or even know it is there. Xrumer and other automated spam systems are programmed to flag sites that present warnings, "gotchas" or alerts, even unusual behavior like loading an unexpected page - allowing the human system operator to investigate why contact us form submissions are being rejected. This information is passed on to the program developers and improvements are added to defeat the blocks. It's why most every anti-spam measure eventually gets defeated. They rat themselves out! Spaminator does not. Why tell them what they're up against?

Q: What about if this becomes widely used, won't the spam system programmers easily defeat it like everything else?

A: We shall see, they'll definitely try. But we've not only thought of that, we've planned for it in advance. Many other features for this are being developed and tested, and some are ready for deployment as the need arises. We don't go into battle with just one or two weapons or ideas.

Tried to purchase multiple times. Was sent to his website to register to be able to buy the item. Was never sent a registration confirmation email after multiple attempts to resend. Even tried to register with another email and nothing. Then, the kicker, I emailed him for assistance and he never replied. This has been over a week ago now. Would never do business with this person, beware.
Perhaps you need to review your account account (chris2) on my site. The account was validated on Jan 27th which was two days after you signed up.
This add-on is amazing! I installed it yesterday afternoon and it’s already stopped over 100 spam emails sent via my contact form.

For the first time in over a year I’ve woken up with not a single spam related email in my invoice from my contact form. 👍
This is a simple, elegant solution that works. Blocked two spam attempts within the first 30 minutes of installing it. Fantastic.
Glad you like the addon and that it is going to help join with the spam. Thanks for leaving a review.
I was a little dubious if this would work as we were getting between 15 and 20 spam emails a day through the Contact form and tbh it was getting a bit tiring adding their IP ranges to the block list as it didn't seem to make any difference, the numbers still kept coming.
Having installed this add-on it has killed spam from the Contact form stone dead, not one has been received in the past 24hrs.
Good to hear the addon has helped the spam issues you were having. Thanks for leaving a review.
I inadvertently left a review at https://xenforo.com/community/resources/ozzmodz-login-spaminator.7443/reviews that I meant to leave here. Here's the original review:

I have just started testing this on three forums I manage and I must say it is very impressive and very effective. Contact Form spam has always been the weak point in Xenforo's anti-spam features and nothing else I tried was able to stop it. Contact Us Spaminator works as advertised. In less than 24 hours, it has blocked more than 30 contact form attempts on the three forums. I don't own the three forums where I am testing it but I will be encouraging all of them to buy a license and certainly the first 24 hours is convincing evidence that they should do so.

It was installed late evening October 17. We are now up to 126 contact form spam attempts blocked on the three forums in just about 48 hours. I can definitely recommend this addon.
Thank you for reposting the review. I am glad you are satisfied with the results still.
