Previously, when you refer to electronic spam it would mean unsolicited emails from advertisers trying to promote and sell all types of products. However, as security companies and anti-spam programs become better in fighting this type of spam, spammers also became smarter and found new ways of spreading spam.
One of the recent tools that spammers are utilizing is image spam. Image-based spam is more difficult to detect than text-based spam so it bypasses most email filters and is spread by millions of compromised computers.
Spammers have found a new way of spreading image spam and that is through PDF files. BorderWare Technologies’ multi-application reputation service called BorderWare Security Network reports of a new trend in PDF spam which are created to bypass current security solutions.
Fortunately, there are tools available like BorderWare’s Intercept Engine which is a blend of anti-spam and anti-phishing tools that provide anti-spam filters, spam-scanning capabilities and other solutions to prevent and fight spam. Intercept Engine is used by more than 2000 companies and protects more than 30 million security systems worldwide.

@Sean – Exactly. They try to learn new tricks and find new ways to get past spam filters and captchas. I’m not sure but with the way things are going, I don’t see spam slowing down any bit.

The spam seems to be getting smarter. They are now able to get past the Captcha image. I just hope they are going to do something about it soon before it gets more out of hand than it already is.
I updated the plugin so if you want go ahead and try it out.
