It is. But it's an interesting topic. :)

We have not seen very much spam or other abusive behavior yet for 
various reasons, but we have been thinking about how to prevent for 
quite some time. See for example:


Per recent discussion on the standards at xmpp.org list, we probably want 
to define stream and stanza error conditions for abusive communications 
sent between domains. I've got a todo item for that somewhere...

Also, be aware that in 2007 the jabber.org service (which runs ejabberd) 
experienced some abusive behavior, and the Process-One team wrote some 
patches to help us deal with that. I'd think that the relevant patches 
were incorporated into ejabberd 2.0, but Mickael and Christophe can talk 
about that.
