Real Time Block Lists

Spam Master implements a new concept called High Availability Firewall that protects your website against dangerous exploits like HTTP and HTTPS DDoS (denial-of-service), SQL injections, brute force attacks and many others threats.

Spam Buffer

Buffer technology greatly reduces server resources like cpu, memory and bandwidth by doing fast local machine checks. Also prevents major attacks like flooding, DoS , etc. via Spam Master Firewall.

Whitelist Exemptions

Spam Buffer Whitelisting excludes spam checks from safe Emails or Ip’s, it also removes these safe Emails and Ip’s from your local Spam Buffer.


Spam Master is a powerful anti-bot shield that easily detects and blocks robotic spam form submissions via real time bot checks. It also detects pesky robots running on browser macros, addons and extensions, headless browsers and browsers without javascript, sessions or cookies.

Administrator Pages Protection

Joyeux Noel 🙂 j'avais beaucoup de problème j'ai du rajouté des firewalls, des bloqueurs de login et aussi Spam Master, il y a toujours des petits malins qui tentent mais, ils sont bien ralentit. Par contre je n'ai pas trouvé c'est quoi la différence entre la version gratuite, et la version payante ?

So far, I have been using this plugin on my main website for over a week, and it seems to work great. This week, I installed it on 30+ of my other websites and I will see how it goes! Thank You!!
2020 ལོའི་ཟླ 5 ཚེས 26 ཉིན།
It is really useless: a.) There are still a lot of spam registrations on my site - b.) In addition, it blocks some real registrations. No need to pay a subscription for this.

Even in trial it does not work properly, but after trial period our site got bombarded with porn spam. Totally useless and I hate your half window size "expired trial" warning.

Not professional at all! While they offer a "free" trial (which you can only find out about by reading the wordy description trying to sell you on it but showing no price, almost all the way to the bottom!), it's not really free, because you have to give them your email to register before you can even use it. no thanks. I get enough spam. If you are dumb enough to go to their site to see what the price is, good luck finding it in the wordier page the link takes you to. There are buttons to buy it, but no prices at all. So click on the button and find it is 9 Euros for 1 site license. 2-5 sites is 31 Euros, and even though there is a button on the main page for unlimited sites, there is no price nor option for such. btw, on their site they have a shortcode showing, so that gives you an idea of how good their coding is....

The plugin works like a charm and is the only one which I found which works seamlessly with AMP (AMPforWP with the Comments and the Contact Form 7 Extensions) and can be used compatibly with the European data protection laws (GDPR). In detail: 1) It works. The plugin actually blocks off spam from my site. 2) Registration - you have to obtain an API key from the website in order to get access, and register the API key in the settings. The pre-delivered API key which appears in the settings right after installation does not work and produces a "level 3" error. In order to register correctly, clear your cache before and after registering the correct API key. 3) What the plugin actually does is to allow some settings and provide access to third party tools, namely a real-time blocking list, and inserts (if set in the settings) Google reCAPTCHA. So, in that respect, it is quite comparable to Akismet, which also does not process content on-site, but remotely in order to determine whether something is malicious. It goes further than Akismet, as it also contains a firewall function and allows to block submissions with Chinese, Arabic, or Cyrillic characters. It also allows to define a number of seconds during which the page has to be loaded before a comment can be submitted. 4) The plugin indeed does not insert any javascript or Ajax, so it can hardly be recognized in code when activated (it sets a footprint by inserting "Website Protected by Spam Master" into the commentary form. Of course, this can be erased by modifying the code of the plugin. 5) Because the plugin does not insert HTML, javascript or Ajax, it is compatible to the AMP plugin AMPforWP (I did not test it with others), without producing code which is not AMP-compatible; different to the plugins "Honeypot for Contact Forms 7" or "Antispam Bee", which cannot be used on AMP without producing page output which is not AMP compatible or produces a form with a field titled "Leave this field blank" on AMP pages. 6) For those who are located in the EU or otherwise data protection aware: It is true that data are transferred to a company called Techgasp, but this company is located in Portugal and thus in the EU. Therefore, all the complicated requirements which have to be met when transferring data into the USA (privacy shield "membership" of the company the data are transferred to and/or Standard Contractual Clauses) are not necessary. As the data are not forwarded for "processing on behalf of a controller" (processing is not done on instruction), an explicit agreement under Article 28 GDPR is not required (my legal opinion). 7) I do not see why it is subject to criticism that a small sum (for European dimensions) has to be annually paid for access to the databases. The plugin enables access to those databases for processing. A PayPal plugin enables access to services of PayPal (which are not free), and the Akismet plugin enables access to the Akismet services, which are also not free (in many cases). 8) If anything seems to fail, clear your cache first. 9) I am not affiliated or otherwise connected to the plugin author or his company. In addition: Suggestion for the privacy statement Processing of Form Entries by a Third Party for Spam Prevention Data which are entered into forms on this website, as well as the IP address, from which those data are transmitted to this website, are transmitted partly or in whole to Tangente da Sabedoria, Unipessoal Lda., Rua Cova da Castelhana, Viv Maria Adelaide, 2765-408 Estoril, Portugal, hereafter called: "Techgasp". Purpose of the processing is to prevent spam to be displayed or received. Spam are unwanted, mostly automatically created bulk messages with unrelated marketing or other unsuitable content. Legal basis for the processing is Article 6 Section 1 Sentence 1 lit. f of Regulation (EU) 2016/679. The legitimate interest which is pursued by this processing is enabling the automated operation of the website, from which spam can only be kept away with unbearable efforts when not using automated checks, as well as avoiding an unbearable load of the inbox which is used for for contact requests submitted through the contact forms on this website. Techgasp use the data under their own responsibility and, according to their statements, not for sale to third parties, but only for the provision of own technical services, for meeting legal requirements, to enhance own services, and to protect own rights. As soon as the data are not required any more for those purposes, Techgasp delete them, according to their statements. Further details can be taken from the privacy notice of Techgasp (provide a link). I also included a statement on automated decision-making in my privacy policy. Automated decision-making is enabled on this website within the context of the functions to submit user comments and for submissions in contact forms. An automated filtering system will check comments and messages received for typical features of spam (unwanted, mostly automatically created bulk messages with unrelated marketing or other unsuitable content). The corresponding filter techniques are explained here [insert a link to the page explaining the plugin]. The scope of the use of the system and the intended impact on the data subject is that it might prevent them from posting a comment on the website or from communicating via the contact form, and that this automated decision will be stored together with the commentary data or comment form data (user input, IP address) and be used for future automatic decision-making in connection with the publication of user comments or the approval of the use of the contact form. The blockage of individual user comments, which is deliberately caused by the use of this procedure, would take away a possibility of publicly expressing an opinion; however, except for special cases, no one has an enforceable right to publish his or her opinion exactly on this website. Blocking the use of the contact form would prevent the use of this feature, but would not affect the possibility to contact the provider of this website through other means, such as e-mail or mail, and thus would not remove the possibility of contacting the provider at all.
