You are a hero and I wish there were more like you.  I am getting
bored with being locked out of more and more websites.

blogspam.net (a FOSS Akismet-like service), manually-maintained
blocklists, trying to design things so that the return on investment
for spammers is fairly low, rate limiting and if you really are stuck,
textcaptcha.com has more ideas and a textual captcha service.

I've been using a combination of those for years and never had much
of a spam problem for long.
