  • spam-bots does not use JavaScript
  • spam-bots are fully automatic and fills all the inputs using typical parsing patterns which can be easily trapped

Two extra hidden fields are added to comments form. First field should be filled with unique code. Second field should be empty. If the user visits site, than first field is answered automatically with javascript, second field left blank and both fields are hidden by javascript and css and invisible for the user. If the spammer will try to submit comment form, he will fail to fill code-input with correct code or will try to submit an empty field and spam comment will be automatically rejected. The Anti-spam Pro input names have random unique suffix what adds extra layer of protection.

Extended license should be bought for Multi-site. http://codecanyon.net/forums/thread/wpmuwordpress-multisite-plugin-licensing/39780 “Yes – they would need to purchase the extended license. Jeffrey”

What about trackback spam?

Users rarely use trackbacks because it is manual and requires extra input. Spammers uses trackbacks because it is easy to cheat here. Users use pingbacks very often because they work automatically. Spammers does not use pingbacks because backlinks are checked. So trackbacks are blocked by default but pingbacks are enabled. You may enable trackbacks if you use it in [Settings] = [Anti-spam Pro] section. You may read more about the difference between trackbacks and pingbacks.
