True. The best way would be a receiving server side captcha. "Before
you can contact this user, please tell me what is the airspeed
velocity of an unladen swallow?" But that would need a new XEP, right?

Yes. As long as inline registration and anonymous accounts are still
considered OK, but only limitation on number of accounts for IP per
hour is required, this is fine.

I agree. One or the other spam message in a while (or contact request)
is not a problem. Last year it was just far too much. Some users of
the Debian XMPP server got around 10 messages a day. Do you have any
idea, why spim exploded last year and is not so much a problem now?
Did admins actually read Ge0rgs manifesto? :~)
