The only way I know is to disable iq:register and provide web-based
registration only (with CAPTCHA). Well, of course, as Yann said, it is
possible to improve in-band registration modules to support CAPTCHA, but
there are too little clients supporting it. Also the good approach is to
register one account per one confirmation email. My bad, but we don't
have such feature on jabber.ru :( Seems like it is the time to implement

xmpp:xram at jabber.ru.
