 To disable logging, use the `pk;log` command with no channel name.
 
+### Channel blacklisting
+It's possible to blacklist a channel from being used for proxying. To do so, use the `pk;blacklist` command, for examplle:
+
+    pk;blacklist add #admin-channel #mod-channel #welcome
+    pk;blacklist add all
+    pk;blacklist remove #general-two
+    pk;blacklist remove all
+    
+This requires you to have the *Manage Server* permission on the server. 
+
+### Log cleanup
+Many servers use *logger bots* for keeping track of edited and deleted messages, nickname changes, and other server events. Because
+PluralKit deletes messages as part of proxying, this can often clutter up these logs. To remedy this, PluralKit can delete those
+log messages from the logger bots. To enable this, use the following command:
+
+    pk;logclean on
+    
+This requires you to have the *Manage Server* permission on the server. At the moment, log cleanup works with the following bots:
+- Auttaja 
+- blargbot
+- Carl-bot
+- Circle
+- Dyno
+- GenericBot
+- Logger (#6088 and #6278)
+
+If you want support for another logging bot, [let me know on the support server](https://discord.gg/PczBt78).
+
+Another alternative is to use the **Gabby Gums** logging bot - an invite link for which can be found [on Gabby Gums' support server](https://discord.gg/Xwhk89T).

 ## Importing and exporting data
 If you're a user of another proxy bot (eg. Tupperbox), or you want to import a saved system backup, you can use the importing and exporting commands.
