summary: 'XEP-0191: Simple Communications Blocking support'
...

Introduction
============

Privacy lists are a widely implemented protocol for instructing your
server on blocking communications with selected users and services.

However experience has shown that the power and flexibility of the
rule-based system that privacy lists allow is very often much more
complex than the user needs, and that in most cases a simple block on
all communications to or from a list of specified JIDs would suffice.

Such a protocol would also allow much simpler user interface design than
the current attempts at full privacy list interfaces.

Details
=======

Simple Communications Blocking was developed to solve the above issues,
and allows the client to manage a simple list of blocked JIDs. This
plugin implements support for that protocol in Prosody, however the
actual blocking is still managed by mod\_privacy, so it is **required**
for that plugin to be loaded (this may change in future).

An XEP-0191 implementation without dependency on mod\_privacy is
available in Prosody 0.10 as
[mod\_blocklist](https://prosody.im/doc/modules/mod_blocklist).

Configuration
=============

Simply ensure that mod\_privacy (or mod\_privacy\_lists in 0.10+) and
mod\_blocking are loaded in your modules\_enabled list:

        modules_enabled = {
                        -- ...
                        "privacy", -- or privacy_lists in Prosody 0.10+
                        "blocking",
                        -- ...
