News item #114; "Comment Spam Filtering" on 08/03/06:|
Well, as you may or may not already know, I've become the victim from some minor comment spamming on some of my old testing pages (which nobody uses anyways), as well as on my message board. To combat the spam, I initially filtered out all HTML code except for the <br> tag. That still didn't work as they just posted the same keyword-filled spam garbage, but with no benefit to them (and continued to do so even after it should be obvious that the links are being removed from their messages). So, yesterday I implemented a two-phase commenting system where there is a "preview" page which shows how the message is going to look before it gets posted. This allows people to fix spelling mistakes, and should send a message to the spammers that their efforts are futile. Also, if their process is automated, then it should cause the process to only take them to the preview page (and not the confirmation page), and result in their spam not being posted. Any comments, questions, or suggestions are welcome.
