Every few days, Cyburbia has been getting hit with what I call a "hammerbot". It's a Chinese controlled bot, visiting from IP ranges throughout the world, that attempts to register an account on Cyburbia once a second, for several hours at a time. I'll block the IP range, the hammerbot goes away for a little while, and a few days later, it's back.
I just modified the site's .htaccess file to block the bot, based on a unique fingerprint of sorts that it leaves behind. If you're blocked, and you really shouldn't be, please try visiting Cyburbia with another browser, and post a note here.
