After an excellent tip from Shloime Henig, I realized that my anti-spamming technique would not work in conjunction to people who have any sort of auto-form-filling functionality running on their browsers. I have implemented a new system that is much more simple. Before blogging about it though, I am gonna let it run for a day or so to see if it effective.
Sorry in advance if it sucks and my site gets flooded with links to adult sites. Fingers crossed :)
