I thought I was safe. I had done most of the smart things to avoid comment-spam: renamed the link to comments, renamed the comment script, and installed the excellent MT-Blacklist
Then today, I was barraged with about 100 comments in a short period of time (I didn’t check how long it took). This was clearly being run by a script. The suppurating sore of a wretch who attacked my site (in violation of terms clearly posted in the comments pages) lives at IP number 188.8.131.52; this traces back to a machine behind the rusonyx.ru domain.
