-# mod_pottymouth
-
-The 'mod_pottymouth' ejabberd module aims to fill the void left by 'mod_shit'
-which has disappeared from the net. It allows individual whole words of a
-message to be filtered against a blacklist. It allows multiple blacklists
-sharded by language. The internal bloomfilter can support arbitrary blacklist
-sizes. Using a large list (say, 87M terms) will slow down the initial server
-boot time (to about 15 minutes respectively), but once loaded lookups are very
-speedy.
-
-#### Installation
-
-On Ubuntu:
-````
-cd ~/.ejabberd-modules/sources
-clone the git repo
-cd mod_pottymouth
-ejabberdctl module_install mod_pottymouth
-ejabberdctl restart
-````
-
-module will be installed in: ~/.ejabberd-modules/mod_pottymouth
-
-#### Config
-
-The file format is as follows:
-
-````
-modules:
-    mod_pottymouth:
-        blacklists:
-            default: /home/your_user/blacklist_en.txt
-            en: /home/your_user/blacklist_en.txt
-            cn: /home/your_user/blacklist_cn.txt
-            fr: /home/your_user/blacklist_fr.txt
-````
-
-For each language (en,cn,fr,...whatever) provide a full path to a backlist file.
-The blacklist file is a plain text file with blacklisted words listed one per
-line.
-
-#### Gotchas
-
-The language will be looked up by whatever value is passed in the xml:lang
-attribute of the xml message. So, any xml:lang value to be supported will need
-a corresponding entry/blacklist in the config file. If xml:lang is missing,
-the 'default' entry in config will be used.
-
-For xml:lang attribute docs, see:

-
-#### Blacklist helper
-
-Thinking of a bunch of swear words and all the permutations can be tough. We made
-a helper script to take a bare wordlist and generate permutations given a
-dictionary of substitution characters:

-#### Tip of the hat
-
-This mod makes use of the excellent 'etbloom' module:
