Yes, that say spam: 0. My blog has no spams after I installed a honeypot spam trapper.
I read a method for catching spam last week, I have deployed it on my blog, and I must say the result is astonishing!
The idea is simple. We add a new textarea (or input type=”text”) field, and we are going to use CSS to make it invisible by setting: visibility: hidden. To the user, they won’t know that there is an invisible field, when they are filling in a legit comment the honeypot will be empty, however to a bot, since they are not smart enough to figure out that the textarea is a honeypot, therefore will add content to that invisible form field.
So on the server side, we will check the content of the honeypot, if it is empty, then we know that it is either human, or the spam bot is avoiding it, however if the honeypot is not empty, then we know it is a bot. This method is effective for the majority of the users on the Internet, unless if someone is using text based browser, or has CSS disabled. This can be solved by placing a passage of text with the similar effect of “Keep the textarea empty”.
Also, another method to ensure that we are always 1 step ahead of the honeypot, we can make the honeypot’s name and id a rolling field, as well as the legitimate fields.

Not sure if spam bot is smart or just got lucky, time to do rolling names on form fields.
