[Chicago] Tech Coffee Suggestion: SpamBayes + Roundup = spam-free tracker???

[skip at pobox.com]

Are there any Roundup gurus in the corral?  The python.org folks would like
to switch the core issue tracker from SourceForge to Roundup.  There's just
one itty bitty problem: wiki/blog spam.  For example:

    http://bugs.python.org/issue1030

I know how to do the SpamBayes side of things but know absolutely nothing
about Roundup (and was told it's a bit of a challenge).  Would someone like
to collaborate on this at Tech Coffee the next few weeks?

Thanks,

Skip Montanaro
