<p>The stanza blocking protocol defined in <cite>RFC 3921</cite> allows a client to control <em>explicitly</em> which senders its server must block stanzas from. Such explicit blocking is suitable for privacy control, but not for filtering SPIM.</p>
<p>This document contradicts an <em>assumption</em> expressed in the standard blocking protocol in order to extend client control to SPIM blocking. More specifically, it simply defines a SPIM recognition privacy-list fall-through action that is different from the 'allow' default assumed in <cite>RFC 3921</cite>. <note>The language used in <cite>RFC 3921</cite> Section 10.2 Rule 7 appears to be deliberately vague (informative rather than normative) in order to permit other default fall-through actions. The protocol defined in this document is therefore (arguably) compatible with <cite>RFC 3921</cite>.</note></p>

<p>The various SPIM recognition procedures that may be employed by the server are beyond the scope of this document. No single measure can differentiate all SPIM perfectly. It is RECOMMENDED that servers implement a combination of complementary SPIM recognition techniques (and other anti-SPIM techniques <note>Other examples of anti-SPIM policies and protocols include: requiring a user to pass a robot challenge before registering a new account, invite-only and/or out-of-band user account registration, providing a standard protocol for reporting SPIM to both the servers involved, server-to-server connection dialback, karma (client-to-server and server-to-server), legal agreements not to send SPIM during user account registration, and IP blocking.</note>).</p>
