This free ClassicPress and WordPress plugin invisibly reduces comment spam.
It does this by adding a hidden field in the comment form, which humans won’t see. Bots will see and fill it, triggering the trap.
The name used for the hidden field can be changed, so that if the bots wise up and your spam increases, you can just switch the name used at any time.
This is a dual-platform (ClassicPress and WordPress) rebuild of our retired WordPress plugin ZigTrap.
