Another Comment SPAM Attack

SPAMThese people just don't know when to quit: I got a note from my upstream provider that my server seemed to be having a real traffic spike last night. At 2am PDT. All of it from the web, on port 80, and all of it involving a Perl script.

This blog is the only thing running on my server that's 100% Perl.

Taking a gander at the logs they sent, I finally deduced the cause: a massive comment SPAM attack by a bunch of bots. All of which failed to post, due to my little bit of obfuscation. But the cumulative effect was that of a denial of service attack on the entire server.

So, once more, I've fudged the writeback scripting - now you won't even see a 'Post' button if JavaScript is not enabled in your browser. Not many bots have JavaScript engines. This should take care of it for a while.

But I have no doubt that this is not the last post I'll make about comment SPAM. Bastards.
