Spam Master


Spam Master was born out of need to protect our website against constant malicious spam registrations and comments that affect the majority of wordpress websites. We did it the TechGasp way… coded a brand new, clean and fast plugin that will make your professional wordpress website safe and clean.

Spam Master protects WordPress based websites from millions of known spam emails, domains, ip’s and words by blocking user registrations or post comments. Uses RBL technology (real time block lists) constantly being updated.

The problem facing spam targeted wordpress blogs is that most of the spam registrations or comments are done by a mixture of “bots” robots and human spamming. Most of the spam registration systems fail including captcha precisely because the human factor kicks in during registration, also these captcha systems “push away” real user registrations and can injure your professional, commercial, sales based website income.

The plugin comes packed with automated Spam Learning function that will make your wordpress blog a fighting spam enforcer by providing registration ip’s and emails for analysis and spam lists inclusion.

Very few plugins will actually show the statistics we packed into spam master. Protection Level, Total Website Users, Total Spam Users Blocked, Total Number of Comments, Total Number of Spam Blocked Comments, Total Number of Approved Comments, Total Number of Pending Comments, Total Number of Trashed Comments, Total Number of Threats you are Protected from, Spam Learning, Status of RBL Spam Servers, User Registrations List with (user id, registration date, user status, name, username, and email) and Comments List with (comment date, comment author, author email, author website, comment content, comment status).

Fast loading, Spam Master is modular… it only loads what is needed to keep your website secure and clean.

Makes no use of Javascript or Ajax to keep your website fast and conflicts free

Poor Support. Confusing registration.

Poor Support. Confusing registration. I paid 2 weeks ago and still don’t have the registration working. No one replied to my last email. No they don’t provide Professional Priority support. Wish I’d gone with another company. Too difficult and not enough help.

Trial ware ONLY – RUDE Plugin author

I find it hard to believe this plugin isn’t violating the WordPress rules.

There are ZERO function that work without an active license. They will give you a trial license that is only good for 7 days. I purposely invalidated the license to see what, if any functions work without it and it seems that they are ALL not functioning.

Trial Ware is supposed to be against the rules.

To top it all off, there are a few reports of the plugin author being amazingly rude and nasty to plugin users. He even called a guy “retarded” here –

I would advise anyone looking for SPAM software to move on to the next option. This plugin seems like a huge scam, is most likely violating the rules AND the author likes to insult and belittle people.

Not Very Effective

99% of the registrations I get are spambots even with Spam Master. Items I put on the block list are allowed to register anyway.

Great program

One of the best spam control i have seen i am using it on my site [Link redacted] I get a lot of spam ,I have just installed this plugin and it has blocked 24 threats in the last half hour
