I turned registrations back on after being off a couple month and within minutes Russian and other foreign and domestic bots were trying to register. It is a real pain to clean up hundreds of fake accounts a day so I have disabled registrations for the foreseeable future. If someone wants to join this site they can email, airmail, phone, walk, run, drive, carrier pigeon, etc.. The real solution is to get a Captcha code incorporated to the registration form. I will investigate this.
