Spam from leaked (?) user details

I get a disturbing amount of email spam addressed to the email address I
used only to register here - rubfor@etc. How have people got hold of
these details?

See above. In short,

ruby-talk mailing list <======> usenet comp.lang.ruby
^


> ruby forums

The ruby-forum is a web gateway to the ruby-talk mailing list.
The ruby-talk mailing list is also gatewayed to the
comp.lang.ruby usenet group.

Our email addresses travel far and wide.
