Combating comment spam on your blog
I was a bit excited last week-end when I received over 250 pending comments. After spending over an hour to read them, my joy fell off quickly because more than 80% comments were spam. Let’s first define a spam according to spam.abuse.net
Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send – most of the costs are paid for by the recipient or the carriers rather than by the sender.
I’m using WordPress for my blog, where apparently there are some solid built-in-tools to prevent comment spam. Plus there are a wide range of comment spam protection and defence plugins and methods to choose from. There is no “one size fits all” method that will protect your comments; spammers use many tactics. Consider using multiple defences. Remember spammers change the way they attack so you must keep your choices updated.
