With the abundance of spam online, it’s not surprising that businesses and organizations have developed ways to combat it. Since spam can be delivered in a variety of ways, there are numerous software products useful in fighting it. We will take a look at three options available.
1. CAPTCHA – Blog comments are often the target of spammers, since a popular blog can provide hundreds or thousands of views to their website, and that can lead to sales. A CAPTCHA form provides a simple test to make sure that a human is leaving a comment and not a computer or “bot.” This test is simple enough for anyone to solve (such as a simple addition problem or reading a series of letters and/or numbers that are distorted), but cannot be done by a computer.
2. Askimet – This software combats blog comment spam in a different way. It checks comments for links. Those links are compared to a database of known spam links and the comment can be blocked if the link included is deemed to be spam or possible spam. It can also be set to block all comments with a certain number of links (which can be determined by the blogger).
3. Email spam filters – Many email services (such as Gmail, for example) provide a level of anti-spam filter. Incoming emails are scanned and those that contain links or terms that are questionable are sent to a “Junk” folder. The recipient can check those emails and determine if they want to have them delivered to their inbox in the future or continue having them marked as “Junk.”
In addition to the services provided by the email service, you can also purchase anti-spam software, such as McAfee Anti-Spam.
Having anti-spam software will help reduce the amount of spam in your inbox and also on your blog, making it safer for you and for your readers.
