As fun as it is to taunt the bot with random garbage, the idiots trying to crawl my git repo have pulled 2GB in less than 4 hours. Which should fit within my monthly limit for my VPS, but is just a stupid amount of data. So for now, I've set the hostname for my git repo to point to 127.0.0.1 instead. With any luck, the bot will try to DoS itself. But at the very least it will stop bothering me for a while. I might turn it back to iocaine at some point. I've left iocaine on the other sites.
By the way, from the access logs, it hadn't even started crawling the garbage links that iocaine generated. It was only crawling links that it had before.
In other news, you'd think that Google would understand about respecting robots.txt. Googlebot seems to do so, but GoogleOther does not.
