So, I've learned my lesson. I received a comment from someone who said they were big like me and asked for my email address to talk. Being the compassionate person I am, I gave it to them. I immediately started getting spam from a company I never heard of and it's getting past my ISPs junk email filter. This is the first spam I've gotten in the years since I've had this email address.
And now I know - never give out my email address to a blog commenter.
If you want to talk to me privately, write a comment and ask that I not publish it.
