The script works but the message on the site states: "This little script will spit out a never-ending list of fake email addresses for spambots to choke on. It will fill their memory up before they can get any real addresses off of your web site"

It's the never ending part which worries me - after executing the script I noticed it grabbed over 50% of the cpu resources on my testbox...

So maybe it's better to use a static spam bait instead.

Why not release it as a separate module instead of a hack so both modules can be used together? So we could use an unmoderated newbb and a moderated one together - the same as the current faqmodule/xoopsdoc module - would be a nice option
