All this is good - and it fits Bot Challenges exactly :)

The sender (and/or its server) should be flagged as a SPIM bot after a
few messages queue up. So I think the server should do this (simple

To continue to be able to send messages to other people without having a
presence subscription and without first being explicitly added to a list
by the other person.
*Your question suggests you may still be considering making
subscription='none' into a list of correspondents that are free to
communicate without challenges? IMHO it's not a good idea:
1. We've agreed SPIM blocking will be handled by the server. But IMHO
servers should not add or remove items from users' rosters or privacy
lists (without an explicit request from the client). So, IMHO, we need a
third list of 'correspondents' that the server manages. To make things
simple, it can even be 100% transparent to the clients (although we
might eventually want a protocol to delete it).
2. I don't want my roster to grow any bigger. Should a mobile client be
forced to download a list of all the user's correspondents, when all the
user wants is her roster?
3. iq:privacy rules do not differentiate between JIDs on the roster with
subscription='none' and JIDs not on the roster.
4. For most people, personal contacts (roster entires) and one-time
correspondents are not the same thing, so we shouldn't mix them.
5. Why not have a third list?
One more question about the above:
Q4: Why is the "plaintext challenge", you mentioned in your point 3, not
in the form too? (see Bot Challenges)
*Can you give us a more detailed description of your ideas of how this
should work? I'm still not sure what you're suggesting as an alternative
to privacy2 - or whatever we want to call it
