You might want to upgrade to the latest version of FMS (0.2.14).  I
found a rather relevant bug, which SomeDude has fixed:  identities
were publishing captchas even when they weren't publishing trust
lists.  If you solved one of their captchas, you would be announced to
them, but not to anyone else.  Given the fraction of identities
publishing trust lists (low), this means that your odds of actually
getting announced are small, at best.  0.2.14 will not download
captchas from identities not publishing trust lists, and won't publish
them if you're not publishing one.

Yes, the captchas are automatically generated on demand; the code is
in simplecaptcha.cpp.  If there was a stock database it wouldn't work,
as a spammer could just harvest the whole database.

I'm not going to continue my brief attempt to make a different captcha
system (though I'll keep running my easier version of the same style
captcha).  There are many far more competent people out there working
on the problem, and the current state of the art appears to be that
the spammers are winning.  There have been some interesting proposals
recently, eg:
http://arstechnica.com/news.ars/post/20080423-researchers-stay-step-ahead-of-bots-with-image-based-captcha.html

My current belief is that captchas are doomed, and some alternate
system is needed.  I have no clue what it is; currently, I think
hashcash might be the best option, as bad as it is.  For now, out of
band introductions are a good thing, though obviously not a complete
solution -- though I can certainly sympathize with your stubbornness
:)
