Good question. I'll answer based on my experience at the jabber.org
service: I think that by "uncontrolled registration" he means in-band
registration ("IBR", XEP-0077) without CAPTCHA forms (XEP-0158). A
service could also allow uncontrolled registration via the web but that
might be more difficult to test. At the jabber.org service we turned off
IBR perhaps a year ago, in favor of web registration with CAPTCHAs. No,
it's not perfect, but it seems to be less liable to attack (or at least
automated registration by malicious bots).
