Okay, I've installed this and it seems to be working fine, but I have some questions.
At first the Baidu spider was hammering us, hitting the site about every 8 seconds, but now it seems to have more or less given up on us. Yandex, on the other hand, seems to have intensified it's attempted crawls. At first it was hitting the site about every 25 seconds but over the course of this install has ranged everywhere from every 1 second to where it's at now, about every 1.5 minutes. The 1.5 minute attempts have only occurred in the last couple of days.
A couple of days ago when Yandex was hitting us every 1 second, we had some server load issues. I don't know if this is related but it seems it might be and I'm wondering if logging the blocks to a text file might be counterproductive in that area, writing to the file every second or so.
Also, Yandex is using the same IP address every time, so I thought it might be best to just block it using the .htaccess file, but that doesn't seem to have had any effect. Is this mod redirecting Yandex before it has a chance to read the .htaccess file or is Yandex simply ignoring it?
