Ah, that might be interesting. You could go even further, kind of like a PGP signature has begin and end comments. You could make it a normal post with useful content, explaining what POCTEST is, etc, etc and then in the body, search for your specific BEGIN and END tags and get the code you want out of that. Could be something like:
BEGIN POCTEST (commands here) END POCTEST
That way it's not a spammy blog post, but a real one. One that also has real functionality in it. Should be simple enough to parse the post looking for the code, as long as it has the right tag, right?
