One of the most dangerous threats to blog safety: unprotected comments.
It must be true because so many people still have captchas attached to the end of their comments. I must be visiting more new blogs than normal, because I have been amazed by how many times I typed words like "phoacy" after I thought I had already left a comment.
So I need to know WHY? Is there some email forward going around stating that word verification will protect you against evil Chinese spammers? Maybe that if you allow the comments to be left it will open your computer to viruses? It's terrifying really. Besides, why make it easy for people to leave comments on your blog? You can challenge your reader's ability to type in random words like "pinest" and keep a straight face.
For the record: I do not have any hatred for the Chinese people. I have a deep respect for all of Asia. I am merely commenting on the Chinese spam I have left on my blogs...
In all seriousness, I got rid of word verification months ago, and I rarely regret the decision. I have discovered that you only get spammers leaving comments if you allow spammers to leave comments. If you delete the comments just after they leave them, they stop leaving them (like gangsters and graffiti). It takes less time to delete a spam comment than it does for your visitors to type in a random word.
I challenge you to try it out! Turn it off for a week! You can easily change this by clicking on "Settings", "Comments", then scroll down to "Show word verification for comments?" and click "NO".
Done and DONE!
