Blocked Bot Profiles modal, found under the Profiles module.

Only include bots you want to block from posting. All real members and bots not on this list are allowed to post.
- Bot Profile Photo Override - when enabled, the user profile photos for bots are replaced on the Companion Site with your Companion Site Icon. However, if a Slack message sent by a bot uses an explicit icon or username override to change the author user’s appearance, this override will take precedence and will be preserved in the Companion Site.
Limitations
- The Slackbot (i.e. user with id
USLACKBOT) is not supported in any user dropdown inputs in the Tightknit app or user-related fields in Tightknit APIs. - In order to sync messages sent by the Tightknit bot, the Post to site message shortcut must be used to manually post the message to the companion site.
