Hi Roy, sorry that I didn't get back to this sooner but
I've just arrived back from a speaking trip. To answer
your question - yes, I have been slack in addressing the
issue of comment spam. This has been due - in part - to
my attention being on other matters - namely
upgrading/rewriting RegExLib.com and building
ProjectDistributor. Very - *very* - soon, the blogs over
at Regexadvice.com will be upgraded to run on
CommunityServer. This will give you the ability to have
a much finer level of control over how comments are
enabled on your blog.
Sorry that I've been so slack about this but we'll get
it cleaned up and then port everything over.
