I, for example, cannot register in forums or comment blogs with KeyCAPTCHA (I am on dynamic IP-address getting "We have detected spam activity, your actions are blocked")
One should also remember understand that by installing KeyCAPTCHA plugin a webmaster (owner) opens the backdoor for executing scripts in his visitors browsers loaded from KeyCAPTCHA.com backservers of professional spammers (with a long list of deceptive practices)

while a webmaster cannot control or even see what is being loaded to his visitors and a visitor cannot even reproduce it (they use for it various tricks like intermittent spamming, only on first couple of min of first visit, on 1st passing, geo-targeting, etc.)
