Spam flood protection

This feature allows you to customize the number of messages a user can send in an open or group channel per second. By doing so, all excess messages from a user are deleted and only the number of messages allowed to be sent per user per second are delivered. This feature protects your app from some users spamming other users in the channel with the same messages.

Note: Sendbird's default system setting is five messages per second. This limit can only be adjusted by contacting our sales team.
