I have a wordpress blog and I had the Captcha plugin on it for the longest time because it worked. Lately though I am getting mass amounts of spam. I then tried to do a “Add These Random Numbers Together” that were generated via PHP but still no luck. I’m not quite sure what I need to do to block this spam but it is quite annoying.
I was reading about some kind of visual script that spammers use – that reads your webpage or something thats why Captcha has the messy images to block this sort of thing. I was thinking that maybe it would help if I put a animated GIF background behind my PHP Random Number Captcha so it would be easy for a use to read but hard for a bot.
Not sure anyway I need suggestions :S
How about using reCAPTCHA? It has plugins that are easy to use (PHP for example).
