Why we introduced CAPTCHAMikey 27 comments
If you've commented within the last day you've no doubt seen a small change. Let me fill you in with a quick history.
Back in the early days of this site when we first started getting hit by comment spam, I vowed to not implement one of those barely decipherable drunken alpha-numeric sequences, or as they are technically called - CAPTCHA.
We all know how annoying they are, so that led us to develop our own solution in the form of a honey pot. The honey pot served us well for a couple of years stopping around 99% of comment spam, but as this blog became more popular over time spam-bots have also gotten smarter, and our little solution is no longer viable.
So now we have implemented our own CAPTCHA, but as you've probably noticed it's not as offensive like a typical CAPTCHA as mentioned earlier, and I've already received an email from one member thanking me for making it easy.
It works on the simple fact that spam-bots do not possess the intelligence (software) to recognise complex images such as a photo, so when presented with a picture of Spock for example, they will populate the field with random gibberish as they always do and be denied the comment.
There is one downside to this though and I did wrestle over it in the first instance. And that is this system is useless to people with visual disabilities. As far as I know we do not have blind people coming to the site, so I went ahead with this CAPTCHA anyway.
You will also notice that registered members are also presented with the CAPTCHA. My decision to do this was based on the simple premise that there is nothing stopping a spammer from registering an account and setting up a script to automatically spam the site, but as long as the CAPTCHA is in place, he won't succeed.
Your comments are welcome :-)
