Yes, we agree. As a result privacy lists were moved out of the core spec and into a XEP (XEP-0016[1]). They are no longer part of the core XMPP specifications[2]. In addition a new XEP was more recently created, to cater for simple blocking of contacts, XEP-0191: Simple communications blocking[3]. Hope this helps, Matthew [1]: http://xmpp.org/extensions/xep-0016.html [2]: http://tools.ietf.org/html/draft-ietf-xmpp-3921bis [3]: http://xmpp.org/extensions/xep-0191.html
