We've picked up another spammer botnet again. Blog spam is now coming in at around one every ten seconds. I am therefore switching off comments on all threads for a while until the scumbags stop tormenting my server and go away.
(The spam is being detected and binned. Unfortunately the process of doing so is machine-intensive — it involves running a CGI script that polls the Akismet servers over the internet, does regular expression matches for spam keywords, executes a SQL database insert, and a bunch of other stuff. There's no way around this bottleneck: it's a side-effect of the blog being designed to support many orders of magnitudes more people reading it than actively posting comments, and it works okay until a botnet with thousands of hosts starts firing spam at it every couple of seconds.)
Based on past experience the spammers were attracted by my essay on what Amazon's ebook strategy means, and they'll go away after a few hours if I block all inbound comments.
Normal service will be resumed presently ... meanwhile I can be found at @cstross on Twitter.
Update: re-enabling comments. Will switch them off again if the spammers are still hammering on the front door.
