I wrote a custom image verification system for an image gallery site I coded about a year ago. It displayed a picture that was stored in MySQL (yes, blob in mysql but they were small images and more secure than sniffing images from a directory), the user just typed out the name of the picture and verified humanity.

Captcha != ftw

i usually find, especially for the e mail spam, that as long as you dont enter your e mail or your information in mailing lists ( i got my explination at http://www.advertisingonlinesite.com/MailingListBrokers.html and so far its held up pretty well) the ammount of spam you recieve declines significantly.

the only exceotion is my work e mail account. recently a virus infiltrated the system and spam is sent from the e mail address of many of my co workers. a big pain.

Just trying to find the time to upgrade/enhance it is so very hard! But, I’m not surprised at all that your CAPTCHA caught more spam than a published plugin… the spammers will always target the published ones first! :)

I removed the email address field from my comment form, and I reject any comment with an email address present. I only used to see a few per week, so my spam-load was nothing like yours, but it was still enough to be frustrating to me.

I don’t expect this to last, though. I set up a captcha on an old UBBThreads forum for someone; prior to doing so, I added a hidden field with a random value, and about 50% of the spambots there correctly passed the hidden field.
