Stop comment spam with some Java script

Filed in archive Anti-Spam Tools on October 19, 2006

Martin Ringlein over at Maryland Media blog has found a handy way to stop automated comment spam in blogs. I know we all suffer from that Pests, so if you're java handy, and even if you're not, check out what Martin has to say, and then get someone do it for you.

He started from the premise that spiders can't read Java script code, and devised a way to use this against automated spam:

"Not knowing (or caring) much about how spiders function with respect to what they actually use to publish in an automated form, I took a stab in the dark and assumed placing my 'submit' element within a JS file would do the trick - hiding the one function required to post.
A month later with absolutely no spam in sight, I can confidently say the solution is working!"
