I’ve noticed a couple of folk lately discussing comment SPAM. This caused me to see if it was possible to maintain my own defences while at the same time making life simpler for the commenter. I may well have found a solution:
bcSpamBlock is a very simple and lightweight way to block the vast majority of spambots from completing web-based forms. For most users (those who have Javascript enabled) it is completely transparent to the visitor. For users with JavaScript disabled, they need to cut and paste a small string into a textbox (similar to a Captcha, except they can copy/paste it)
So, those of you using browsers with Java enabled, you may comment without seeing any defences at all. If not, then you need to copy and paste the relevant text.
Let’s see if it works. If not, I can always go back to the challenge question.
Anyway, this is what you will see with Javascript enabled:
And without:
Boo!
It worked, then 😉
I’ll give it a try on my blog, thanks for the tip.
