Subscribe!Over the last few months or so, I noticed an alarming amount of comment spam being posted here at the Libloggery. Some stories seemed very popular with the spambots, but I think I've found a way to defeat them in the pollxn comment program. At least for the time being.
I "hacked" my pollxn.cgi script to read the response to a math question a commenter must answer before submitting their comment. So, if you don't answer the question or answer it wrongly, the comment will not be accepted. This might not be the best way to do it, but I do hope it will reduce my comment spam. If you'd like to see specifically how I implemented this, feel free to comment or contact me.
