Just a quick question as a matter of interest: How much spam do the forum moderators, and the Debian.org maintainers get?
Do they find it necessary to use aggressive spamfiltering on accounts, or not?
Reason I ask is that I run an email security-awareness site, and one issue we're looking-at is the harvesting of 'mailto' hyperlinks from webpages and its relation to spam volumes.
Just to clarify I'm referring to email spam here, not robotic forum posts.
