Comment Spam
I added comments to TellThemWhatYouThink over the weekend. As an anti-spam measure, I included a text box asking people to complete a simple sum to prove they were a person. This was for two reasons:
- It’s very quick to implement
- It’s more accessible than an image captcha — the sum will be read out by screen readers
Unfortunately, though, it doesn’t work. Be warned! Spam comments started appearing on the site within hours of the new functionality going live.
I’ve replaced that system with a reCAPTCHA test. It has an audio test for blind users — I hope it’s sufficient. We shall see how it fares!
