Updated SpamFilter Definitions

This is just a quick note that I have updated the spam definitions for SpamFilter.cfc. So, if you are using SpamFilter.cfc and have the second argument of init ("getNewDefs") set to true, simply re-initialize it and you will have the updated definitions.

SpamFilter 1.1

Since I first released SpamFilter, I have added several new spam definitions to it without needing to touch the actual code. The most recent addition, however, did require me to update the code. Since I did that, I decided to go ahead and make another change to take advantage of new functionality in DataMgr 2.2 (on which SpamFilter 1.1 is dependent).

Preventing Form Spam in cf_sebForm

I use cf_sebForm for all of my contact forms. Form spam is a constant problem for those forms. So, I set up a generic way to do filtering in those forms and wrote both cf_sebForm and SpamFilter.cfc to follow the same guidelines.

Add SpamFilter.cfc to BlogCFC

BlogCFC does a good job of preventing spam, but I sometimes get comment spam that I think SpamFilter.cfc could prevent. I decided to see how easily I could implement it on BlogCFC.

It turns out that it is pretty easy. I had to add a few lines to Application.cfm and addcomment.cfm. The drawback here is that I will have to repeat this process when I upgrade BlogCFC, but it is pretty painless.

SpamFilter.cfc Goes Gold

I have been using SpamFilter.cfc to prevent form spam for nine months now with great success (and no user impact). Other than some new spam definitions (including one in this build), I haven't made any changes in a while - no bugs or problems to be fixed.

SpamFilter.cfc Beta 2

I just made an update to SpamFilter.cfc and I am releasing it as 1.0 Beta 2. This is a result of some spam that I have gotten on the contact form of my web site despite having SpamFilter.cfc working against that contact form. I really have to thank those spammers for helping me improve the product.

Prevent Form Spam with SpamFilter.cfc

I was told last week that a client's contact form has been getting a lot of spam - on the order of 30 a day. We had a simple spam prevention measure in place, but that clearly wasn't doing the job. It was time for something a little more sophisticated.
