I think the one thing that many people forget is that they are a cheap, easy way to help keep spammers out. Take something simple like posting anonymous comments on a web site. This raises the effort required to comment spam my site just enough that most comment spamers won't bother. If they do bother I'll put forth the effort to block them and remove their comments. ~Paul On 8/24/05, robert () webappsec org <robert () webappsec org> wrote:
