I decided to use an edited version of the Foo captcha to see how it goes and in a week I've had nothing.
I was getting 5-10 a day combined no matter which Captcha I used. (I never used an outside service though)

Here's what I did
1. Created an image in photoshop that has nice large readable text. Something easily read that looks
nice on the page too unlike text captcha images which people hate.

2. Created a block and using regular html added the image to it.

3. Set that block to Anonymous users only and only the registration page or site wide.

4. Edited the foo.module (file found in the Captcha pack) line 57 changed the word 'foo'
to what I put on my image.

5. On line 60 I changed 'Enter "foo"' to something that will direct the users eyes to the block I created.
I used 'Look at the "secret word" block on the right side of the page and type the
word you see'

This obviously wouldn't control human spammers but it sure frees up my time to deal with them manually.

Think this will stand the test of time or am I just wasting mine?

But have you tried the Captcha Riddler module before? I know that there's no version for D6 yet but perhaps you have some experience with the D5 version?

Riddler was the very last Captcha I used before I jumped to D6. I guess it would be easier to do what I did with that since no file editing would be necessary. I just wanted something less annoying on the user side and more reliable than regular captcha and with D6 foo is the one that's working for me so far.

Hopefully that module gets ported to 6.xx but for now this seems to be working. I do think that bots are so smart now that a riddle itself would be relatively easy to pass unless you add an extra twist.

Thanks for you're input
