In the last month, there have been well over 400 attempts at spamming this journal. All have failed. And yet the spammers still try. And I get email notifying me each time, because there's always a possibility that a legitimate comment might get classified as spam and need to be manually approved.
Ah well, I have the IP for each of those 400-odd spams, and using routeviews.org I can easily turn them into a considerably shorter list of netblocks. And then auto-create a shitload of
Deny from rules. 104 of them, to be precise. It will be interesting to see if the spammers notice their lack of access and keep trying.
