Making honeypots invisible
This is the essence of catching the bots. The idea here is to do something to keep the honeypot fields from being visible (or tempting) to people, but that bots won't be able to pick up on. There are lots of possibilities. As you can see from looking at my comment form, I've simply added a style attribute that sets display:none, but there are lots of other ideas:
* Use CSS classes (randomized of course) to set the fields or a containing element to display:none.
* Color the fields the same (or very similar to) the background of the page.
* Use positioning to move a field off of the visible area of the page.
* Make an element too small to show the contained honeypot field.
* Leave the fields visible, but use positioning to cover them with an obscuring element.
* Use Javascript to effect any of these changes, requiring a bot to have a full Javascript engine.
* Leave the honeypots displayed like the other fields, but tell people not to enter anything into them.
