When I first started writing web CGI code more than ten years ago, web spam wasn't a problem, but I knew it was just a matter of time before it became a serious problem. This is the problem with any open (non-authenticating) communication system.

For quite a while, I could easily spot spam in the comments and remove it. However, these days the spammers have gotten quite sly, extracting text from other comments and merging their links into it. Such comments no longer look like spam.

I realize that my little captcha method wasn't great to stop all spam, but it did help eliminate the simple spambots. I used this method because I wanted to avoid generating images (for some other reasons.) I suppose I'll need to upgrade to REBOL/command and start generating real captchas images at some point.

Today, I took some time out from 3.0 work to add a new comment review method. When you look at the main page, you will see links that allow you to review comments for the week or for the month. Those pages will also let you mark abuse of comments, and those entries can be reviewed and removed if necessary.

So, give it a try. If it works out, I'll move it to the other blogs.

PS: I'd like to thank Didier Cadieu for his spam reporting over the years. It helped to know where the spam was being posted.
