[COREblog-en] comment spam

[Hermann Klocker]

I am getting comment spam on my site - entries filled with links to web sites
offering the usual crap.

How can I prevent this? I do not want to turn off comments - they fill my blogs
with very nice conversations.

Sorry if this has been answered before - found nothing/I am a newbie.
