Is there a channel setting to ask for confirmation if a member does @here?

Question

Is there a way to make Slack ask for confirmation if a user makes a @here mention in the channel? I heard Slack does ask for confirmation for @channel mentions.

Answer 1

There won't be a built-in feature to configure this but we could build a custom app to mimic what you requesting. When someone posts a message, we can modify the @here to _here and suppress it. Then, our custom app should prompt whether they would like to really notify everyone who is online now. Upon their confirmation, we can modify _here to @here.

If modifying messages did not work, we could delete and repost after user's confirmation.
