What other blog software do not require Login/Captchas for commenting?

I am currently aware of WP, NucleusCms, Wwwboard and Guestbooks that do not need Login or Captcha on the Comment forms.

Besides these, what other Blog software do not require Login/Captchas for commenting?

Hey... its been a few days since I posted... I'm sure some Blackhat guru here must know about the blog software that I asked about :hmmmm2:

I'm not asking for Blog urls, Code or hand-holding... I just need an insight into what other blog software have you guys come across that does not require Login or Captcha for commenting?
