Reading, Writing, and Arithmetic

I've been encountering some really silly software lately. I was trying to visit the homeland stupidity blog, with Safari and the most-excellent pithhelmet, and I get this message:

This is broken. I'm trying to read. My request is well-formed HTTP. Bloggers like readers, right? If you're an attacker and trying to blog spam in some way, this doesn't help. You'll add a referrer header. Blocking some URLs that come in without an HTTP referrer header might help a little, but all this does is lose you readers.

I don't know who's to blame for this really ill-considered software, but it blocks me from visiting URLs I've bookmarked at a couple of blogs. Oh well. You've lost me as a reader. So, homeland stupidity, no link for you. Not knowing the difference between reading and writing means you don't me as a reader for your blog.
