The amount of people doing their own internet crawlers never ceases to amaze me, nor does the utter stupidity of some implementations.
As a nice (and utterly satisfying) follow-up to breakfast, I just banned the nether regions out of IP address 220.127.116.11, which is running some piece of crap known as rssImagesBot/0.1.
As usual, that particular bot ignored robots.txt (or seemed to) and didn't understand BASE HREF, so it got itself caught in an infinite loop, requesting URLs like blog/blog/blog/... and making my Apache throw a fit (not to mention the waste of otherwise perfectly good bandwidth, since it was constantly making requests, without any sort of pause).
All for the sake of assembling a dumb page with the images it got from crawling.
I don't care how cool it is - it isn't coming back here.
Oh, and have a nice day.
