I've shut off the comments features of this blog for two reasons:
- No one I knew was commenting
- The last 150 comments I got were spam advertisements for either prescription drugs or porn
I can block IP addresses from being able to post to my blog, but that just slowed them down a little rather than stopping them. I quickly went from 9 IP addresses blocked to 52 in one week. That was a big hassle to delete all the spam comments and enter the IP address to block it. So I just turned off commenting.
I'm going to try to see how leaving the commenting on for the most recent entries works. If I continue to get spam comments, I'll turn it off completely.
