I had a blog for a while and used Wordpress as a platform (the software, not wordpress.com). One of the first things I did was to set comments to require moderation. It was more work for me, but that simple setting avoided the problems you're talking about. There are WordPress add-on packages that are supposed to catch the spam comments, but I'm not sure how effective they are. Moderating the comments caught 100% of the potential problems.
Between that and the constant hacking attempts from Russian IP addresses, running the blog was an interesting and enlightening experience... |
