[IMC-Tech] Captcha implementation: which way to choose?

[Ringo]

I'm not sure about these specific plugins, but I do remember looking
into akismet before and realizing that simply setting apache to not log
IPs (or scrub them) wasn't sufficient. IIRC Akismet and many other
systems get IPs through a PHP command which can't be fixed with a simple
change to the config file and/or have the form send things directly to
the anti-spam service.
