Gack! More trackback spam!
Well, it looks like testing out the IP banning plugin for a few days was a good idea, because it didn't work quite as well as I'd have hoped. In other words, I'm still getting trackback spam.
I took an hour or so to rework the plugin. This time I decided to keep it nice and simple. I made sure to remove all extraneous whitespace, separate the per-blog and global IP lists, and did the check with a simple preg_match() call. This has the added benefit that I can now use the same code to ban an entire subnet just by including a star in the IP.
I think I should also include a setting to turn off trackbacks and/or comments altogether. I'll bet there are a lot of people who just don't feel like trying to keep up with the spammers. And at this point, I really can't say I blame them. My site isn't even that popular, and I've gotten nearly 50 trackback spams just since I implemented e-mail notification the other day.
