About This File

No CAPTCHA, no questions, no counting animals, no puzzles, no math. No spambots signups, no spambots posts.
Hook uses invisible tests to stop spambots at the IP.Board.
Anti-spam features of the hook

  • Stop spambots at registrations.
  • Stop spambots at the topics.
  • Contact form protection (CAPTCHA should be disabled!)
  • Allow guest posting on the forum without CAPTCHA.
  • iPhone/iPad, Android app to control registrations and posts on the board.

Anti-spam hook info
We have developed an anti-spam hook for IP.Board that would provide maximum protection from spam and you can provide for your visitors a simple and convenient form of posts/registrations without annoying CAPTCHAs and puzzles. Used to detect spam multistage test that allows us to block up to 100% of spambots.

Low false/positive rate
This hook uses multiple anti-spam tests to filter spambots with lower false/positive rate as possible. Multiple anti-spam tests avoid false/positive blocks for real website visitors even if one of the tests failed.

Spam attacks log
Service CleanTalk (this hook is a client application for CleanTalk anti-spam service) records all filtered comments, registration and other spam attacks in the "Log of spam attacks" and stores the data in the log up to 45 days. Using the log, you can ensure reliable protection of your website from spam and no false/positive filtering.

Real-Time Email Address Existence Validation
It is very important to be sure that the user used his real email address. Spambots very often use fake email addresses, i.e. which addresses do not exist. Non-existing email addresses also entail several other problems for website owners:

  • You can never contact them by email,
  • The client will never receive any notifications from you (account activation letter, password recovery, email distribution, notifications, etc.),
  • If you use email marketing for your clients, then a large number of nonexistent emails in the mailing list may result in your IP address being added to various blacklists of email servers.

CleanTalk will check email addresses for existence in real time.

Blocking  disposable & temporary emails
Block fake and suspicious users with disposable & temporary emails to improve email delivery. So, it also prevents malicious activity, spam bots, and internet trolls.

Private blacklists
Private blacklistsAutomatically block comments and registrations from your private black IP/email address list. This option helps to strengthen the protection from a manual spam or block unwanted comments from users. You can add not only the certain IP addresses but also a separate subnet to your personal blacklist.

Blocking users by country
Automatically block comments and registrations from the countries you have set a ban for. This option is useful in cases of manual spam protection and for protection enhancement. If your site is not intended for an international audience and you do not expect comments/users from other countries.

Blocking comments by "stop words"
You can block comments which contain "stop words" to enhance spam filtering and messages with obscene words blocking. You can add particular words or phrases.

CleanTalk has an advanced option "SpamFireWall". This option allows blocking the most active spambots before they get access to your website. It prevents spambots from loading website pages so your web server doesn't have to perform all scripts on these pages. Also, it prevents scanning of pages of the website by spambots. Therefore SpamFireWall significantly reduces the load on your web server. SpamFireWall also makes CleanTalk the two-step protection from spambots. SpamFireWall is the first step and it blocks the most active spambots. CleanTalk Anti-Spam is the second step and checks all other requests on the website at the moment of submitting comments/registers etc.

How SpamFireWall works?

  • The visitor enters to your website.
  • HTTP request data are being checked in the nearly 5.8 million of the identified spambot IPs.
  • If it is an active spambot, the bot gets a blank page, if it is a visitor then he receives a normal page. This process is completely transparent for the visitors.
  • All the CleanTalk SpamFireWall activity is being logged in the process of filtering.

Private blacklist for SpamFireWall
It allows you to add individual IP addresses and subnets to SpamFireWall. It blocks the attacks from IP addresses which are not included in the SFW base yet. This option can help to block HTTP/HTTPS DDoS, SQL, brute force attacks and any others that made it through the HTTP/HTTPS. You can add not only the certain IP addresses but also a separate subnet to your personal blacklist.

The CleanTalk is premium anti-spam for IPS4, please look at the pricing. We try to provide the service at the highest level and we can not afford to offer a free version of our service, as this will immediately affect the quality of providing anti-spam protection.

Should I use another antispam hook?
Use other antispam hooks not necessarily, because CleanTalk stops up to 100% of spambots. In some cases, several anti-spam hooks can conflict, so it will be better to use just one plugin.

Very impressed with how effective it is. I've gotten a few false positives. I opened a support ticket and within 10 minutes they tuned the algorithm to eliminate the false positives.

5 stars for customer service: quick responses and very helpful.

For the past few days, based on comments in another topic, I've been using CleanTalk.org to help filter spam.

Overall, it's been pretty great, and I strongly recommend it.

The Pros:

  • It's greatly reduced the amount of time my moderators need to spend working and moderating posts, users, etc. by flagging them as spammers, issuing warnings, etc.
  • It stops posts as well as registrations.
  • It has a relatively simple interface that lets you mark things as NOT spam.
  • I haven't seen any false positives yet. Those, as you can imagine, are MUCH worse than false negatives as real users can get upset.
  • You can block entire countries from posting and/or registering.
  • Their database seems to be fairly large and/or complete, resulting in high accuracy.
  • I haven't noticed any slowdown of posts.
  • It's pretty darn inexpensive.
  • Established members don't seem to have their posts vetted. That's good.
  • I'm able to remove CAPTCHAs and other things that reduce the odds of a valid user registering and posting.

The Cons:

  • The first night, I got a 502 Gateway error every other or third time I loaded up the log. This hasn't happened since.
  • There's not as much transparency as I'd like. I don't even know right now how many posts a user has to make before they're considered established and their posts aren't scanned.
  • https://community.cleantalk.org/index.php Their forum isn't particularly busy. Which could be seen as a good thing…

I posted a topic here to discuss it more:

Looked like it would do the job, easy enough to install and not expensive, but that's about where the positives end.

It has literally managed to block zero spam, hasn't managed to stop a single registration getting through of which there has been 20+ in the last 2-3 weeks all signing up from similar areas, with outlook/Hotmail addresses matching the signup name and proceeding to post 10-15 threads of Chinese spam containing links.

Flagged them as spammed on cleantalk after manually being dealt with, have been told they're "manual signups/posts"

they're clearly not...  hopefully it will improve

This really is a pretty effective plug-in. Pretty cheap and certainly well worth the money.

Seems to block many spam registrations and also attempts to use contact forms and so forth – but doesn't get them all. However it certainly extremely helpful and cuts down the amount of work every morning trying to check who has been in overnight to try and cause you damage.

Very easy to configure a registration as spam for future use by Cleantalk so that the more people use it and take an interest in it, the better it gets. But don't expect it to put in an end to all of your problems but it will certainly help you handle some of them – maybe most of them.

It also allows you to configure a spam firewall to exclude people from certain countries. Rather unfortunate that this is necessary but when the overwhelming number of spammers seem to come from those certain countries, – in the end you have to do what you have to do.

Although in its default settings it's pretty easy, if you want to set up additional personal configurations then it isn't hugely intuitive and take some getting used to.

I suppose that the user interface could be a bit easier

We recently switched to Invision Community from another software, where we had extensive spam plugins due to bots.  After switching to Invision Community, we ended up getting blasted almost immediately with spam accounts.  After getting this plugin, we went from 5 bots per day to 1 per week.  I'm happy with the results.

Excellent tool for protecting forums. Reduces spam registrations & posts to practically non-existent. We've been using the service since May 2018 & it's helped massively reduce our workload in dealing with spammers & spambots.

I've been using Anti-Spam for over a year now and even switched forum software in the process and it's always worked very well.  Prior to Anti-Spam, I'd have to manually screen new registrations daily, not that's all done automatically.  Very happy customer!

Tried it out for a year (+ some free months) and it recently ran out. I had no intention to continue it, but I discovered increasing spam AND they have a great 3 year offer so they baited me again 😄

Great service.
